Tomorrow's the 15th Annual Bike to Work Day! Cycling activists anticipate 150,000 participants tomorrow. If we had a bike and worked at an office, we would most certainly be participating. Also, if we lived west of Divisadero, we'd take that awesome Wiggle route. We hear it's the place to be.

Energizer stations will be set up in nine Bay Area counties, in which you can stock up on free beverages, snacks, and "good cheer." Here's a list of all the SF stations. Be sure to keep track of Bike to Work Day on Twitter, and enter their raffle, which runs through May 31.

Have questions? The San Francisco Bicycle Coalition (SFBC) has organized Commuter Convoys throughout the city to get the newbies feeling comfortable. Push-off time tomorrow is at 7:45 a.m. They've also set up a Bike Buddy Forum online. (The forum might be a bit overloaded at the moment though -- we couldn't get it to load.)
