We saw 1000's of racing messengers from all over the US and Canada. I also happened to even catch 2 friends from Texas! They were racing, and I didn't even know they were messengers.
Also we caught the Chicago Critical Mass, which was a totally strange but familiar feeling, riding bikes with a few hundred others. The crowd was relatively timid compared to any LA scene. In Chicago they call out "Happy Friday" to pedestrians, and Brad and I were goofing around with this theme. We had a number of variations for the riders, none of which were appreciated.
Also we played at an open mic at The Gallery Cabaret which I think scared a few people. Really cool though was that we met Joe from the Rat Patrol and he told about Saturday's party they were having. It was a miniature version of Bike Kill, good times. I got drunk and talked at strangers.
LA scene has way more energy than Chicago's, but I am glad I caught these events. It was a big bike weekend in Chicago.
