Only FMM tourist cards are needed nothing else. You MUST get them right exactly at the border or face lots of hassles and fines further down. You may or may not be checked for tourist cards at the 28th parallel monument near Guerrero Negro.
We means multiple folks and if all your motor vehicles have license plates you should not have an issue. There is a completely new crossing at the border so slow down and pull over for your immigration documents. A "S" curve is involved.
Many new stores south of Ensenada. Vizcaino has grown into a small town with paralellos (frontage streets) stop lights the whole she-bang. Many many highway improvements the biggest one south of Ensenada just before Sto Tomas. They did a bang up job leveling the grade and straightening the curves. Many vados between Vizcaino and Sta Rosalia have been "wide bridged" you'll smile. Same between Sta Rosalia and Mulege. Remember the "serpentine" stretch 75 miles north of Guerrero Negro with winding road, guardrails at the edge of the pavement and a nagging fear of meeting an oncoming 53' big rig? Well, it's gone. More smiles. The new El Boleo mine and refinery and huge pier just north of Sta Rosalia comes as something of a shock. As is the jammed downtown area. Mulege remains sad after too many floods. Loreto just got hammered bu a tropical storm. We also got 7" of rain way out here in the bone dry Vizcaino peninsula.
San Lucas is no longer a town. it is a city. A big one. Well at least as far as the peninsula is concerned.
You'll love it...
