Went to a Martial Arts class for a while here. Got involved pretty heavily, became a yellow belt. The instructors were great and the people were awesome!

Unfortunately, I don't remeber any of the vocabulary except through anime-induced flashbacks.
Unfortunately, I don't go anymore because it was a 30 minute drive and I have a busy schedule. For a while, a VERY busy one.
It was great while it lasted though. One of my best friend went a year before I went and he says he loved it too.
