It turns out you shouldn't always rely on Google Maps. 

Tuesday morning we went on a hunt for the river. The Rio Grande serves as a natural boundary between Texas and Mexico. It's an area where there is no wall for many miles in either direction.

I drove down a dirt path that Google stated is a public road. It was extremely narrow. No room for two cars. There were times when I had to slowly, and barely, dodge major ruts. The Stooges' "No Fun" played on the stereo as I half-joked we were going to drive up on a bad situation or encounter Border Patrol.
