Then we drove down main street where we saw as many cars with Mexico plates as Texas plates. There are a lot of duty free shops along here where you can find a lot of junk.
After leaving main street we took a back road back to Harlinger. This road followed the US Mexico border. See the fence, we drove up to the opening only to run into a farmer that standing by his truck while his cattle grazed. The fence at this spot is inland from the actual border. Yet in so areas of the fence, there were towers with cameras mounted with spot lights.
Once we made it back to Harlingen, we drove to the old section of town to see the Harlingen Murals.
We weren't able to get pictures of all of the murals.
