It’s the weekend before Thanksgiving, but don’t spend all your time prepping the kitchen for all that cooking. There are things to do and people to see, and the young ones are tugging on your coattails to get out. It’s a good weekend to hit up the Golden Gate Park, with the Garden Railway Exhibition opening at the Conservatory of Flowers on Friday, in celebration of the park’s 140th anniversary. If you’re feeling ticklish, catch a Ticklish performance by comedienne Marga Gomez at La Peña in Berkeley. And, of course, holiday fairs are in full swing, with the likes of the 2010 Holiday Bazaar at the Mountain View Senior Center in Mountain View offering live entertainment, shopping, and an ornament contest. Here’s more on what’s doing around the Bay this weekend:
