Where can I get a cheap riding helmet?

Borrow one tonight and go to the tack store tomorrow. Your school, or friend, or instructor should have one for you to use but, put a tissue in the helmet before use just in case. Lice sucks and you don't wanna risk it. Keep track of the new helmet and write your name on a piece of tape and put it inside. You gotta do what ya gotta do. I put purple nail polish on the butt of my crop so I can identify it. It actually looks pretty good!
