The father of a friend of mine, always a bit of clown, has now significantly upped his clown quotient by taking on a new hobby with the name "cowboy action shooting." Yes, this is a hobby, based on dressing up and shootin' like a cowboy. There are a stunning number of clubs for these people. Yes, there are multiple webpages, here is a clearing house.
Kind of a combination of Civil War reenacting and the Village People.
