Join an urban scavenger hunt in the historical Gaslamp Quarter of San Diego, traveling aboard a party bike navigated by a driver-guide. Two teams of six to eight passengers compete against the clock during this 3-hour experience — akin to the CBS reality TV show ‘The Amazing Race.’ With your group, complete three missions by pedaling around the area to gather clues. You’ll stop for photo ops and to purchase drinks and bites (own expense) at several bars along the way.
