I've been low level in a B-52 near Hastings Nebraska in the IR route.. in
the turn at 500ft AGL, and had a C-172 go under me.

I've also flown the IR Routes in Wyoming and Montana while in B-1s, I've had
traffic cross co-altitude near Powell Wyoming again, abotu 500ft AGL. In
Montana, at least the crop dusters put out NOTAMs they were there, so we
could bump our minimum altitude up to 1000ft AGL and go over the top of
them. Yes, we spotten more than a few.

Yep, call Great Falls flight service and ask if the MOA's in the eastern
part of the state are hot and you get this mish mash of times they are
hot with all these different altitude. Screw it, going right thru the
middle.
