This is the first time I’ve ever been in Texas and not in DFW airport. Our mid-course correction took us to this least visited National Park and was it ever worth it!  Our first stop after 20 miles on a dirt road was Santa Elena canyon.  Here we hiked up the mighty Rio Grande to the top of a slot canyon looking at Mexico on the other side of the water.  it was pretty amazing! We drove for two days seeing the beauty and remoteness of the place.  We got to Bouquilles canyon and had another view into Mexico. The Rio Grande continues to underwhelm!
