For all intents and purposes...
For all intents and purposes (language,food, efficiency,etc...) you're in Mexico already.
Also, if you're not a local, and venture outside of the tourist areas, don't be surprised by brusque treatment. There are some very nice people here, but the town is rather backwards, and the locals are muy defensive and provincial. They are not used to American efficiency. After all, 1/3rd of the town was born across.
