The entrance to the BICAS community bike shop. They sell reclaimed, used bike parts, and offer classes to anyone for a nominal fee. I feel that the existence of a community bike shop in a city means the city has reached a "good" status for bicycling and people who ride bicycles. Walk down the ramp into the basement of a building into an industrial area.
These shops tend to make bicycles and bicycle-specific knowledge available to anyone who seeks it out. More essentially, it invites everyone to attend and learn.
If you thought Working Bikes and West Town Bikes were cool (for Chicago people), then BICAS is like the two combined and on steroids.
I love how colorful this shop is.
