On our way to Del Rio, to pick up Tucker, we had the unusual experience of getting within 100 feet of the Mexican border. I am not sure if you are up to speed on what a wonderful place Mexico is right now, but to save the gory details; it is bad, not safe, and the drug lords are taking over. Basically, the border between the US and Mexico is not safe. Needless to say, I was nervous getting so close!
On our way down, we saw miles and miles of ranches. Hunting ranches. You could usually tell what kind of ranch it was by how tall the fence was. The taller the fence meant the bigger the game. Tall fences prevent animals, namely big game deer, from jumping out and going onto someone elses's ranch. Texas ranch owners own thousands of acres of property and charge top- dollar to go hunting on their ranch.
Here are some examples of what the ranches looked like, along with an example of a gate entering the ranch:
The more we drove, the more I noticed side "roads" along the fence lines of these ranches. I asked Kyle what that would be for, and he explained that those "roads" are there to look for footprints. Not animal footprints, HUMAN footprints. They drag along those roads and then Border Patrol drives along looking for fresh prints in the freshly dragged road. If they see some, they can assume some illegals managed to cross the border and are somewhere in the ranch property.
This is an example of one "road" I was able to get a picture of:
When we got to Lake Amstad (where our puppy was at!) we had to take the dam access road. (All lakes down in TX are man-made, usually a dam of some sort). We accidently missed the road and ended up driving on top of the dam, getting us within 100 feet of the Mexican border. Here are some pictures I took while my tummy started doing flip-flops! Once we passed a border patrol vehicle and came close to the lookout towers, we turned around!

On the way back to San Antonio from Del Rio, we had to drive through a Checkpoint. All traffic must pull into this "station," roll your window down and talk to the officers on border patrol. (They check for anything unusual or suspects.) They commented that Tucker was a cute dog! It was an interesting little road trip, but next time Kyle and I plan on driving the OTHER direction!
