I guess my take on his take is that my reasoning of his reasoning is that there is no reason why we shouldn't be able to cross over to the little hamlets in Mexico w/o having to go to a legal point of entry. It's the same "concept" of being able to ride the Rio Grande. Why can't we just fill out a little customs declaration form when we go over and come back - something like a "crossing permit" - just take the river permit and mark through river and put crossing. Go over and have some tacos, ride the donkey's into town, pay the man for the river crossing in his flat bottom boat, etc. The good ole days.
You got it!
