Thanks guys, I do have the paperwork showing the registration has been paid, but no actual license plates. As I said, we bought the car new in January, I would sure hope they would arrive by mid July when we leave Zihua for San Diego, but it sounds like it should be okay even if they don't.
I don't have a Mexican drivers license yet, I've been planning on getting one but just have been too tempted to stay at the pool/beach. I will get on that this week.
Talley Ho, a drink would be great, we are also in La Ropa, at the top of the hill in Cerro del Vigia. Our treat in exchange for picking your brain.
