Spent a couple hours in a converted warehouse that's a coffee shop now in downtown Tulsa that I found on prior business trips. Again on business, I was lucky enough to be in town when I knew they had an open mic night. House rules say all material must be written by the performer, so I wanted to see what local artists can do. I brought my sketch gear to keep me company. Turned out to be a fun night. Performers were approachable, the audience was supportive of their talents and I had some nice sketch time.
