I've only been to SD four times...love the place, but don't really think of it as laid back (but then again, I've never lived there). I haven't been to Miami since we used to hit Ft. Lauderdale for college spring breaks...no desire to either. BTW, I thought SD was "Northern Tijuana
". IMO, any place that's packed with people (SD included) just doesn't fit my definition of "laid back".
