A three hour walking tour of downtown San Francisco architecture with Rooftop’s very own architect dads Greg Mottola and Tom Sprinkle. Together our tour guides have more than 40 years of experience and opinions about our beloved cityscape. This is not a historical tour, but a survey of buildings that Greg and Tom fine the most interesting–and the most awful.

After they’ve exhausted all of their knowledge, the group will relax at a bar near Market Street for post-tour drinks and snacks. November 2nd, 2-5pm; $40/person. Contact 415.729.4581 for tickets or sign up online.
