Do anything you want blindfolded. The possibilities are endless!!
It's high noon, the Wild Wild west is WILDER than ever. Simple dare, 2 blind folded people, 3 paces back, turn around, and "FIRE" I'd say have a pre-determined amount of shots....but, do what feels right :) Just GO FOR IT!!! "Go Big or Go Home" ;)
have a boxing match with one of your mates blindfolded
