Mark your calendars for April 22, when Orinda Rotary celebrates Earth Day by participating in Orinda Action Day. Club members will join other community volunteers to clean up, refurbish and otherwise beautify Orinda's downtown. Participants will meet at Orinda's Library Plaza, roll up their sleeves and get to work between 10:00 AM and 12 Noon.  Snacks and a light lunch will be provided courtesy of the Orinda Community Foundation.
