We love a party here, especially a party for a cause. There are some great fundraisers in the mix this weekend: SF faves’ Charity and the JAM Band bring the noise for Noe Valley Nursery School; and Tree Frog Treks holds a combined St. Patty’s Day party and silent auction. Think green! For more St. Pat’s fun, visit Habitot’s Shamrock Day with a treasure hunt throughout the museum and potato stamp art projects. (Potty) Dance it up with Ralph’s World at one of its two local shows (SF and Walnut Creek). And after a year and a half of renovations, Happy Hollow Park and Zoo in San Jose is open again sporting new green facilities. Run down and take a closer look at this new old favorite.
