If your Sat afternoon is free, there is the Love Fest parade that goes from Embarcadero to the Civic Centre. It is a celebration of electronic music but I understand it is quiet a sight still given it is SFO.

Also do 'bear' in mind that as it is the Fulsom weekend, bars arounding the Fulson area will be very packed on Sat night.

Fulsom is 11am to 6pm so make an early departure to Alcatraz to get the most out of Fulsom. It does finish on the dot of six as they have to clear up.

Have fun.
