Hello all, My name is Ed and I am from Boston. During the weekend of July 18-20 I will be visiting San Fran in order to watch the Giants play on the 18th. I have the better part of 3 days to kill and I was wondering if anyone could point out some nice attractions to check out while I'm in town. I plan on doing Alcatraz but other than that I have no plans. So any suggestions would be helpful. Thanks!
