I watched a bit of men's slow-pitch on Saturday. The pitchers wore helmets and shin guards. The batters were crushing the ball and there were, apparently, few restrictions on the bats they could use.
I wear a lacrosse helmet and street hockey shin/knee guards. How hard some 6 plus foot, 250+ pound dude can hit a pissile at you on a ball that's only lobbed to him.
I need to work the next day.
