I hate to disagree with you, Mike, but considering all of the crankup horror
stories I have heard, I must. Each new story tells of yet another way a
crankup can "get you". I am convinced that I have not heard all the
different ways yet and I have heard dozens of them. Crankups are inherently
dangerous to be around and I, for one, can't anticipate their next attack
plan. I don't think anybody can . . .
