I love riding bikes in San Francisco. I ride my bike to work and school every single day. It is great exercise and generally faster than cars and buses. Last Friday, I decided to go to Critical Mass with some buddies.

Critical Mass is an event typically held on the last Friday of every month in cities around the world where bicyclists and other self-propelled commuters take to the streets en masse.

As I was heading down market street with hundreds of other cyclists, I ran into Kelly and Chris (Revision3 interns!).  I knew they were going but I was highly doubtful of actually running into them. We cruised with the pack of cyclists and had a great time.  I know that Chris was blown away and was laughing the whole time.  Shot a quick video as well:

Have you ever ridden critical mass? Do you ride bikes? Let us know in the comments.
