20th Annual SLO County Creeks to Coast Cleanup

To reserve a ticket ($30) and purchase a paint kit ($35) visit Foreverstoked.com
Recommended materials are - Canvas, paint (dark and light colors) and a small set of different size brushes. There will be a 15 minute guest speaker leading into the start of the painting.
