Glacier People at my college do that all the time. One time a girl almost got hit twice in two different places because she wasn't even paying attention .-.
Worst horseback riding injury I have sustained was bruised ribs, but I want straight to urgent care because I wanted to make sure everything was ok. I'm a wimp though.
We had a guy in the ER the other day who broke 9 ribs in a horseback riding accident. Bro went home first for a couple hours even though he had a collapsed lung. What a cowboy! XD
