One Tam

A victory over the weeds
Mt. Tam Day of Thanks - Hosted by One Tam

In light of the current tragedy in Butte County and poor air quality, we are shifting our Day of Thanks volunteer day and replacing it with Day of Thanks: Camp Fire Donation Drive. At the Mill Valley Community Center we are hosting a mini donation drive for the Camp Fire relief effort and a poster making session to welcome back the Marin County Fire Department.
