Bay seniors interested in expanding their celebrations of Spring beyond Easter and Passover might want to try out Holi Day, the riotously colorful Hindu festival. The Bay Area’s growing Indian community invites you to join in the music, dance, food and most uniquely, the pelting of scented powders at one another. There’s a dustup in Dolores Park on March 10, in Stanford and in Sunnyvale. If you’re interested in dressing for the event check out the sari stores all over the Bay Area. There are a couple of blocks of them in Berkeley on University Avenue west of San Pablo.
