Cowboy Action Shooting

I searched and didn't find a thread for this. Does anyone participate in Cowboy Action Shooting Events? Do they have them in WI? It looks like something that I'd like to get into closer to retirement. 

My sons used to go to Bristol when they were young with my ex wifes father. They also had one in Holman.

Used to trapshoot with a guy who was into it, however that was close to 20 years ago.  If I recall, there was a place in either Dousman or Oconomowoc.
