There is another performing group in the Santa Barbara area, out at UCSB: Improvability. They have two shows on Friday nights. The first show is at 8:00 pm, and the second show starts at 9:30 pm. I've not been to a show myself, but folks who have say that the show is great. Also, I've worked with one of the players (Tawnie) as a member of Caught in the Act and she's a wonderful improvisor, so go check out a show. I just revisited their website and they had a big 24 hour improvathon over the June 2-3 weekend, but the site hasn't been updated since then (other than some unfortunate spam on their forum). So, it's possible they are off for the summer since it's a student group.
