Who Needs The Chargers When You've Got The Xolos? 

www.stubhub.com/club-tijuana-tickets/performer/1503209/ Is one place to do it -- I think you can also buy them at the stadium, either way it's worth it to go down there and check out the situation first hand -- the casino and parking lot parties and nearby taco shops etc. are all worth making the trip even if you don't have tix yet. Good Luck!
