Flagstaff?My own pretrial deal with a set always was, once you're ready to roll make sure the set will roll backwards. If not at first, somewhere in the yard before you go out the gate. This situation, maybe just a tad bit of inexperience got this driver in trouble. Previous posts about backing set up to free shoes from drum, all good advice. Last resort, beat the damn shoe with a hammer. One of the reasons I moved to AZ.
