Nixternal - I'm sorry to hear that. I only happened to catch 2 guys drinking. There is a definite hipster crowd (which doesn't describe me in the slightest bit) but I was surprised to see how many other random people were there also. My first ride I almost suspected to be odd man out in the crowd of hipsters but there was a nice mix.
As it turns out, a friend and I are going to ride in Critical Mass tonight.
