This will surely get some replies. OK, Trump and many say we americans must build "The Wall" along our 2000 mile border with Mexico. Trump and some act like it can be done by next week. I always scoff when I hear this, though I support building one more than most. Theres only one catch here. Obviously None of them have traveled along the Rio Grande through Big Bend National Park and many miles upstream and down. How the heck do they think we can "build a wall" along here? I've spent weeks, solo, paddling the river in my kayak. Its like a mini Grand Canyon in sections. There is NO WAY we could build any kind of wall along this 500 mile section of desert river. It'd be cheaper to post a full time sniper at each side canyon. The actual middle of the river water IS the border. Floods?Not gonna happen. And building a wall everywhere BUT the canyon country will just funnel all the illegals into this one area, ruining one of our best wild National Parks. So... what say you guys?
