Awesome view of the canyon. Its a shame that it narrows down so fast and you can't hike in any further. I guess a canoe or raft is in order if you want to see the canyon in depth.
Didn't feel all that safe there at the border and it is true, they never patrol the border, they patrol US 90 2 hours north. Well worth checking out. It is Big Bend so it must get at least a 4.
Bonus Mexican serenade!
