Stockton Earth Day event takes place at Victory Park behind the Haggin Museum on Pershing Avenue, between Argonne Drive and Picardy Drive. It starts at 10 am until 4 pm on Sunday April 23 and entrance is free. This Earth Day Festival has a long history of helping people recognize the importance of caring for our Planet and its natural resources. It is also an opportunity for the community to get together and address environmental issues that affect us locally and nationally. Sierra Club members are welcome to join us for 2-3 hours of tabling at this community event. Contact Margo Praus to sign up for volunteering. Or just swing by our table and say "Hi!" and be sure to visit all the other booths with conservation and environmentally friendly ideas.


Tracy Earth Day Event will be held on Saturday April 29th from 9 am to 3 pm next to the Farmers Market on 9th and Central,  downtown Tracy. The theme this year is on the power of the Bike. The California Highway Patrol will host a Bike Rodeo and kids will receive a free bike helmet (while supplies last). There will also be E-bike vendors at Tracy’s first ever bike show. Ride your bike to downtown Tracy and join us.
