<p>There was no waiting ambulance in the driveway. I descended the
stairway, twelve metal steps railed in on both sides, feeling grateful
for what she'd said right after I kissed her. "Don't worry about your
wife. If Wendel tries to make us send for her we'll find a way to roast
him over a slow fire until you're together again. There are three
doctors who will put up a stiff fight and I'm going to set to work on
all of them. You've no idea what a hospital can do with just the right
kind of delaying tactics."</p>
<p>It took me less than two minutes to half-encircle the driveway, take
the turn she'd recommended and strike out for the Colony between the
towering gray walls of the aerators.</p>
<p>The Big Grayness. I'd seen photographs of that tremendous engineering
project in my hell-bent-for-adventure years, when I'd sat at a desk
in a schoolroom, and imagined what it would be like to take part in
the construction work, standing on a dizzy height with an electronic
riveter in my hand, watching blue lights go on and off and sparks fly
up into the cool Martian night beneath a wilderness of stars.</p>
<p>The reality was very much as I'd imagined it as a school kid, except
that I wasn't a construction worker looking down over it, a human fly
with a man-size job to do, but a guy that kid wouldn't have recognized,
his footsteps echoing on the catwalk at the base of it. I had a
giant-size job to do, but how could he have known it would some day
turn into anything <i>that</i> big?</p>
<p>It wasn't even a project anymore—half of it still in the blueprint
stage. It was completed and the towering gray walls were firm and
solid, and the grills were sending oxygen spiraling out over the Colony
without making me feel light-headed at all.</p>
<p>Right at that moment I'd have welcomed a little oxygen intoxication
but the aerator-system didn't work that way. The flow was regulated
directly at the source, kept under controlled pressure and diffused
outward high up by rotary circulators. As it spread out over the Colony
it was drawn down to breathing level by another system of circulators,
stationed at intervals about the Colony and extending twenty-five miles
out into the surrounding desert.</p>
<p>If you wanted to experience oxygen intoxication you had to strap a tank
to your back and breathe the stuff in through a tube in the old way.
But no one in his right mind would do that deliberately, for an excess
of oxygen can be five-ways dangerous on a planet where what you have to
worry about most is over-stimulation.</p>
<p>There were catwalks on both sides of the aerator walls, with a central
lane wide enough for vehicles to pass in opposite directions. I kept
to the right hand side all the way to the Colony, and it took me about
thirty minutes to get there. My strength amazed me. It probably wasn't
quite up to par. But I only had to stop twice to rest and then only for
a minute or two.</p>
<p>Two ambulances passed me, their red tail-lights blinking, but the
drivers didn't even turn their heads as the vehicles went droning
through the Big Grayness. Up above the sunlight was waning, and
turning red, but only a diffuse glow filled that two hundred-foot-high
artificial cavern.</p>
<p>Three aerator-system workers, walking shoulder to shoulder, gave me a
bad jolt for a moment, for they had the look of Wendel police agents.
I encountered them just beyond a break in the cavern wall, where a
cluster of pre-fabs with children playing in the yards made five or six
acres of stony ground resemble a manufacturing town suburb Earthside.</p>
<p>I should have known better than to be alarmed, because the three men
approaching me looked eager and expectant, as if they knew that a few
steps more would bring relaxation after toil and the warmth and glow of
a family reunion.</p>
<p>But they had the husky build and sharp-angled features of Wendel police
officers and I stayed alert until one of them came to a dead halt and
looked me over genially. "New on the job, aren't you, Buster? Don't
remember having run into you before. They keep putting on so many new
men it's hard to be sure."</p>
<p>"That's right," I said. "I live about two miles further on."</p>
<p>"Well, it isn't the best job in the world, Buster, as I guess you've
found out already. You get sucked into a grill sometimes, and breathe
nothing but oxygen until you feel like a blue baby they're trying their
best to save, even if they have to fanny-whack him to get the stuff out
of his lungs for a week or two afterwards."</p>
<p>"Don't discourage him, Pete," the tallest of the three chided. "You
have a cold, cold heart. It doesn't happen often."</p>
<p>"You bet it doesn't ... or my wife would have been a widow long before
this. Well ... good luck, Buster. Be seeing you around ... I hope."</p>
<p>I felt so relieved I didn't even resent the "Buster." He was just a big
grinning ape who liked to kid the living daylights out of his fellow
workers, whenever he thought he could get away with it. No harm in him,
and though there might have been times when I'd have been tempted to
take a poke at him ... I had no such impulse now. I just wanted to be
able to look back and see him dwindling in the distance.</p>
<p>I ran into only one other person before the Big Grayness terminated.
She was a stout, matronly-looking woman carrying a baby and she nodded
and smiled warmly when she saw me staring at the infant, as if she
wouldn't have at all minded if I had been its father.</p>
<p>For an instant there flashed into my mind the nerve-relaxing picture
that every normal male has of himself at times—the humble-station
husband, big-bosomed wife picture. You're Mr. Run-of-the-Mill, just a
simple guy, working hard at a lathe or feeding processed food tins into
a vacuumator. You come home at night with no worries, kick off your
shoes and she's there to make the creature comforts seem important.
A good meal on the table, fit for a king with a hearty appetite—do
kings ever have that kind of appetite?—children romping all over the
house—a round half-dozen upstairs and down—and the kind of night's
sleep you don't get when you have responsibilities weighing on you. The
top-echelon kind that can drive you half out of your mind. It's there
for the taking if you really want it, if you don't wear a silver bird
on your uniform when they add up the score and ask you why in hell you
haven't done better?</p>
<p>It's not quite an accurate picture, because that kind of guy has
worries too—plenty of them. He has to buy shoes for the children and
grin and be tolerant when his wife turns shrewish, as every woman with
a large family and a big grocery bill is bound to do at times. But
still, when you balance the good against the bad, who gets the most out
of life—Mr. Run-of-the-Mill or Mr. Big?</p>
<p>Well ... however much I might fume about it ... I had to be what I was.
I could honestly say that I'd never had any driving ambition to be the
kind of Mr. Big Wendel was. I just had a kind of inner compulsion to
be true to the best that was in me, to preserve my integrity and use
whatever wild talents I had to enrich human life and have some fun
while doing it. If I couldn't always have fun, if illness or death
or just plain bad luck prevented me from living life to the full and
enjoying it ... I'd known that when I'd cut the cards, hadn't I? You
have to play whatever cards destiny hands you.</p>
<p>Just before I reached the last quarter mile of the aerator marathon I
passed another dwelling section, with more kids scampering about and
three or four women standing in the doorways of the pre-fabs. They
didn't look big-bosomy, but slender as willow trees and very beautiful.</p>
<p>I certainly wasn't running, but it was a marathon in my book, the
walking kind where you keep your body held rigid, your arms bent
sharply at the elbows. There was only one good thing about it. I didn't
have to worry about out-distancing the other walkers, because it was a
one-man marathon.</p>
<p>I came out into the biggest square I'd ever seen. The one opposite the
skyport I'd crossed with just as much tension and uncertainty mounting
in me an eternity ago on Earth was just about one-fourth as large, give
or take a few square yards of shadowy pavement.</p>
<p>In a way, the Big Grayness was still with me, because there were
gigantic, interlocking shadows everywhere and although there was
nothing but open sky overhead spirals of wind-blown sand were swirling
across it, half-blotting out the waning sunlight.</p>
<p>When you're sure that Death hasn't played his final trump or even
relaxed his vigilance and you could be yanked right back to confront
him at any moment a square as big and empty and desolate-looking as
that doesn't give you any support at all.</p>
<p>All right, there was life and movement in it, if you want to call a
long line of tractors standing end to end on the far side, one of them
snail-active, life and movement.</p>
<p>One of the trucks seemed to be backing up a little and edging out from
between the others, but I couldn't even be sure of that before an
ear-splitting blast of sound and a blinding flash of light shattered my
last link with the sane universe.</p>
