I have a co-worker who does roller derby. She's come in to work with some pretty big bruises, and sore, but she says she really enjoys it and she skates with a good group of ladies.
It looks a little too rough for me. I'm not really interested in contact sports, but apparently, my co-worker has a good time. She said the best part is they're not looking for Hooters girls -- they really prefer bigger women because they need people not easily bowled over. Makes sense to me.
