One more trip today to the New Mexico Department of Motor Vehicles yielded a successful application for Bob's driver's license. He, too, is now in possession of the NM document, making this branch of the family tree now 100% New Mexican.
As the clerk handed him his temporary license and returned all his identity-supporting documents, I asked, "Did we pay you?" We were surprised at her response--no charge since this is a one year license. Once a driver reaches 75 in New Mexico, they must renew every year. We had known that, but didn't know that there would be no fee for his license from now on. Welcome news!
