San Diego has a great transit system. Their red trolleys will be operating on an enhanced schedule during the Comic-Con…and get this: There will be a costume contest at what their announcement describes as "the Klingon-themed Gaslamp Quarter Trolley Station." This is a contest which at least half the people I've seen on Los Angeles bus lines could win.
But never mind that. If you intend to use their Metropolitan Transit System during the con, then this is the page for you. Thanks to Scott Marinoff for alerting me to this.
