Take a break from that The Good Wife (or any of a jillion other shows, jeez) marathon this afternoon to get some real life drama, at today's San Francisco City Guides tour of the Embarcadero Skyway. Even better, it's free.

"Tread on buried ships that once housed saloons, jails, stores and brothels," event organizers promise, as guide Rob Spoor takes you through "Rockefeller Center West." You'll be seeing an urban oasis you never knew existed!

There are a lot of stairs in this tour, so if you can't handle that, then this might not be the activity for you. Otherwise, meet Spoor and your tourmates in front of 400 Sansome Street at 2 PM today, and prepare to be dazzled.
