I can't understand how that happened. I'd think it could be fixed with some good glue and clamps. What make of bow is it?
Is the folded back piece from the back of the bow? If so I would have thought the string and string tension would have help it in place. I still can't figure out how it happened.
"Oh, crap!" generally means things aren't good, and I see your situation is true to form. I hope you have a good backup plan for hunting season. Good luck.
PM me your address, I will send you some TT limbs like to get you through the season.
