What to do Columbus Day weekend in the San Francisco Bay Area

What to do on Columbus Day weekend in the San Francisco Bay Area? Here are some ideas:

-Check out Art SV/SF, an international contemporary and modern art fair at the San Mateo County Event Center October 8-11. They'll have more than 70 international art galleries and artists, and the fair is for all ages. There's a Kids' Center, a supervised playroom on-site for kids ages 3-13, where they'll be introduced to art and can participate in art explorations, games, puzzles and storytelling. High school/college and art students can attend panels and discussions about art (GoPro’s President Tony Bates will be on the Architecture, Art and Interior Design panel). It's a big fair, with more than 12,500 attendees, collectors and buyers last year, including George Lucas!

-Jack of All Trades Market, with 90+ local artists, collectors, makers and more, plus games, live music and workshops for all ages. It's at Historic Jack London Square in  Oakland on Saturday from 11 to 5. It's free and pet friendly.
