Any cattleman who tells you he doesn't have his own cattle protected by fences is not really in the cattle business.

You can get a good idea of what a lot of Texas/Mexico border is like by calling up Del Rio, Texas on Google.com and then look at the border area from above.

There's a river. Much of the river has a road along its length on the US side. Same over on the Mexican side but the road isn't as well used. Kind of mirror images. There are places where the road doesn't follow the road but cuts across the bend.

I looked at several hundred miles of river and didn't find one single cow ~

Mu, I live in Texas and have traveled along the border. I'm very familiar with the terrain.

As important as fences might be to cattlemen, they don't put fences between their cattle and the only water for fifty miles.

But how many sheep and goats did you count?

From Del Rio north, you're more likely to find sheep and goats than cattle.
