There are two movies/documentaries that we are aware of that cover the history and issues related to mountain biking in Marin. The sad fact is that both movies are old, 1999 and 2010, and not much has changed.
Trails, a film by Satchel Cronk and Will Baker Robinson. Lisa Luzzi, the founder of Access4Bikes is interviewed extensively.
Sharing Mt. Tam
This is a great movie produced by Tom Boss and Stephen Frederico about the history of mountain biking in Marin and how we got where we are. Unfortunately, since the movie’s creation in 1999, we’ve had limited success overcoming those who were in power in the 1980’s and successfully banned bikes from the trails of Marin.
