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.

Enjoy a free, family-friendly, celebratory event with music, food, and much more. Attendees will also have an opportunity to learn more about the next chapter of the national parksite, contribute your own creative ideas, and just have some fun.

The Family Campfire is one of the best ways to support Parks Conservancy youth leadership and education programs, trail maintence and habitat restoration, native plant nurseries, and so much more.
