Tri Delta Transit was so excited to meet “the Garden Girls (G.G.s)” from Brentwood this morning. They came to get Bay Area Clipper cards for a trip on Bay Area Rapid Transit to S.F. to go to Ghirardelli Chocolate Factory and Tunnel Top park. They were excited to hear about the new Tri MyRide service coming to Brentwood in August too. Have fun!
