Of course the services available are convenient. There is a very neat and secure self -storage facility on the highway around La Floresta, which is handy for leaving stuff you don't want to haul around while traveling. Also, a Mail Boxes, Etc. through which one can have letters and packages mailed from the States to a Box in San Diego or Laredo, and then forwarded quickly to one's Box at Lakeside. Small supermarkets are loaded with U.S. products and there is a lot of social activity. English is spoken almost everywhere which makes it OK, I guess, for folks who won't bother to learn Spanish.
Most folks seem to have phones and internet hookups are readily available.
One could almost be living in Arizona. Kind of like Sun City - South with inexpensive household help. At lot of places are on the market and I wonder what will happen to this market when the next recession hits the States and folks have to dump their high priced Mexican hideaway to raise cash. All in all, not the Mexican experience I am looking for. A harder drive than we expected.
