It seems to be a new thing (maybe because I've been hanging around AQHA riders) but what's with the whole "Hold each split rein in a hand and then wiggle my hands way up by my boobs" style of riding?
Similar to this:
All the girls at the barn I was riding at did it and would ride around with their hands way up in the air like that. I was taught to never let my hands move very far above the pommel...
