Big Bend National Park,,,,in Southwest Texas....in the middle of nowhere.....very unique area.....various rock formations, varying desert landscapes (depending on altitude) and odd-shaped mountains....great hiking....Loved seeing the Rio Grand (boundary with Mexico....threw a stone across the river to Mexico...Mexicans call it Rio Bravo....so for 5 days I sang that song (it's a Dean Martin song from the movie of the same name)...Worth the long distance to get there....
