I am a girl jock--or at least, I used to be. (Lately I'm a slug.) I've had experience in my years with all sorts of sporting equipment: bats and rackets; balls of every shape and size (get your mind out of the gutter); court shoes, running shoes, and cleats; baseball pants, tennis skirts, volleyball shorts, and the infamous "shiney hiney" basketball uniforms we had to wear in junior high; sports bras; goggles--you name it, I've participated in the sport and I have at least passing familiarity with the equipment.
Having a boy in Little League changed all that. I had to buy a cup for the first time. You can read about my humiliation in my guest post in The Little League Coach, entitled Cup Stories.
