We are in the Rio Grande Valley of Texas. We are about 10 minutes from Nueve Progresso, Mexico, where the Winter Texans eat, shop, drink, eat ship and drink. One can drive across the border or park in one of the large parking lots and walk across the bridge. (Great exercise to work off the food and beverage.) If one is not in to shopping, eating and drinking, you can lay out by the pool or do one of the other dozen things. These parks have it all. After June 1st a passport will be required to go across and return. The RV parks here in "the Valley" call all of the visitors "Winter Texans." We have been coming dowin here for about 20 years, before we started RVing. If you do not like 84 degree days in January then this is not the place for you. The Canadians love it here.
