Travel Guide: San Francisco Bay Area

Golden Gate BridgeAs promised, here’s a thread for our next travel guide installment. This week’s location of choice is the San Francisco Bay Area. (Boston was last week, and I’ve been writing about New Jersey for two days, so it’s time to switch coasts.) If you live in the Bay Area or have visited, please leave comments about things to do and see (especially, but not exclusively, LGBT- and/or family-friendly activities). What are the famous sites that are worthwhile? What are the obscure gems the guidebooks forget? For kids’ activities, what age range will find them most attractive?
