All are welcome and all kinds of bikes are welcome! Ride your bike from wherever you are to the East entrance of the Bell Tower (not the Kerrytown bell tower, the one at 881 N University Ave). This is where they have free bike valet service - http://a2sf.org/event/bike-nights/
Don't check it in just yet. Look for me wearing a red shirt that says Ann Arbor Adventure Club. We'll head north to pick up the B2B trail and take a short ride to Parker Mill County Park. After a brief break we'll ride back and check our bikes. It's about 5 miles each way.
We don't need to go fast, but hope we get back in time to hear Captain Ivory: http://a2sf.org/event/captain-ivory-2/
If you stay at the festival for a while, it will get dark. Be sure to have a light on your bike for the ride home, and bring a helmet. Please call if you're running late -[masked]four-5187
