You bring up a good point, what definition of a B.O.B. are we talking about? My definition covers bugging out of where I'm at to ANY location to get away from where I'm at, and I don't limit myself to 72 hours (yes...this is a holdover from my Y2K and teotwawki days, just can't seem to shake it <img src="/images/graemlins/wink.gif" alt="" />), but if you're shooting for getting home from work, I would imagine you could get by with MUCH less.
