Just wondering what special bike events there are in your community.

I'll go first. Every 1st Thursday of the month is Bike Night in San Luis Obispo. After the Farmer's Market (that happens every Thursday evening in downtown) ends around 11 o'clock, a bunch of cyclists take over the downtown streets and keep circling about 8 blocks for however long they want. I've only seen it once, and never done it, but it's a ton of fun.
