Gee, Nick, I have a hand-carried acetylene torch that will cut an
inch of steel and will fit under my jacket. Not the point at all.
I doubt that one would find someone toting around either tool in the
infield of Indy for long before someone noticed. The point is to
lock up the generator using big enough chain and lock that your
average "booster" won't be able to cut it. I know that if someone
wants my genny badly enough, the genny is history. I simply stack
the deck in my favor.

The freon/hammer trick does not work - unless the steel has
previously received oh, 10E20 RAD of neutron irradiation so that its
nil ductility point is raised into the range of what freon can
achieve. Something we worry about in a nuke plant's reactor vessel
(cold cooling water, not freon); I don't think it's much of a
concern for a chain and lock.
During PE magazine's days, the question came up regarding "The Club"
that we set up a test to see what it would take to make The Club's
lock brittle. Freon doesn't even come close. Liquid nitrogen does
a fine job, however, but only on some of them. Apparently they had
a bad batch of heat treating. With proper heat treating, even LN2
had no effect.
So if you see a guy walking around the campground with a dewar of
LN2 in his hand, perhaps you ought to call the police.
