Not too shabby! I had no idea that Pittsburgh had an Improv theater. It's in the basement of a church, but it works. It's a very small venue so you should get there earlier to get a seat in the front. I went on a Monday where apparently admission is free!
There were 3 groups that performed for 20 minutes each. I'm no improv connossieur but I admire these folks for getting up there and putting themselves out there like that. It takes some serious courage.
Of course having been to Second City in Chicago, you can definitely notice some differences in the talent, scene transitions, and humor...but it's a start! I like that Pittsburgh offers something like this and there's a community that rallies behind it - very cool - extra star for you Steel City Improv Theater!
