""Critical Mass" San Francisco is lots of fun and serious for some. Everyone is invited! No one is in charge! Body paint, optional."

The days are shorter and a little cooler. An extra sweater or layer is always a good thing to have whether it's foggy or clear. Reflective gear can help keep you safe!

The Critical Mass ride is lots of fun and serious for some. Some use it as a protest against road dangers to cyclists. Others use it as a great way to meet other bike lovers in the city of all ages.

Remember, the ride route is posted on the website every month. You can avoid the traffic jam if you're in a car or enjoy the site and take a few pictures. A little patience, and planning, goes a long way.

On the last Friday of the month, the ride starts in at Justin Herman Plaza at the base of Market Street.

As they say on their site: Everyone is invited! No one is in charge!

Even if you don't have a bike, you can grab one at one of the many popular bike share stations around the city for a small fee.
