Hi - I'm jumping into this thread because I'll be in SD next month for a week and was thinking of crossing the border, just to do something different.

Thanks to KevinS for the thorough tips on Tijuana! As someone who's a frequent visitor to MEX, speaks Spanish fluently and is more interested in culture than boozing and the purchase of tourist schlock, would there be enough in Tijuana to hold my interest for a day? Or are there any other places near the border that might be more worthwhile?

One complicating factor is that I won't be renting a car, so I'd have to get around by public transportation. I have no problems whatsoever taking a trolley or bus to the border and then jumping on a Mexican bus.

Thanks for any advice!
