airport if you fly out.
You will need a passport to get the Tourist Visa, but other than that you don't need one to get into Baja. Although you are supposed to have a passport with you when returning into the USA, I have NEVER herd of anyone not being allowed back in to the states without one. Sure you might have to go to secondary inspection, and you might be delayed a little bit, and you will get a bad attitude from the Border Patrol/Customs guys but fuck those assholes anyway! Jajajajajaja!
..give thanks for the info and link
