What is required to get in and out of Baja without having issues with the local authorities?
To get in Baja? Nothing. Make sure your Gerry cans are empty, or you will be sent to the front of the return lane to the U.S.A. where you will have to give the gas away before you are allowed back to Mexico. They don't want people importing gasoline, junk computers, junk clothing, junk cars, etc. The Authorities are cracking down on this more and more, but enforcement is uneven...
To return to the U.S.A., you need a positive I.D. such as a Driver's License. On Jan. 1st, 2008, you will need a Passport.
If you plan on visiting the interior of either Baja Mexico Sur or Mainland Mexico, you will need a Tourist Visa and $28. I had to pay this fee when I went on my High School Senior trip to Mazatlan, Mexico. They stamped my passport as well. No big deal at all...
What kind of mishaps did you have and were they fixed on the trail?
Busted Oil Pan - repaired w/J.B. Weld & bar of soap.
Stuck in ditch - pulled out w/yank strap.
Stuck in canyon - pulled out w/winch.
Blown BFG AT/KO sidewall - changed tire on the trail.
I'm going back in April with the Mrs. - this will be our 5th Anniversary/'wheeling trip!
My wife and I are going down to Baja, Mexico tomorrow morning to buy some art at a gallery (owned by a Jeeper), and we'll play on the sand dunes when we get done. Should be a good use of spare time while out of the country...
