Some years later I and the "fam" including only my oldest son vacationed in South Texas because our school vacation was in March/April. We drove to Padre Island to be as far south as possible that time of year. It was essentially Spring Break but school kids hadn't discovered the Island as a party spot yet. We Camped in a vacant public campground on the Island, and drove on the beach sand.
When we left we followed that border highway all the way from Brownsville to just short of the Big Bend Area. We ate our meals at local family owned cafes and tried all the home grown chili tacos, burritos and things we never heard of before. Then we angled north toward Alpine Texas where a high school buddy of mine lived. We stayed at a public campground outside of Alpine and that is where my second, youngest son was conceived. 4/2 - 1/2. As we neared Colorado from Amarillo we entered a snow/ ice storm that made our camper so heavy we had to drive in a lower gear just to keep up speed. And that was in a full sized K5 Blazer with a 350 cid v-8 motor. And if thats not right, it ought to be.
