You don't mention any proposals for how to deal with it so just presenting the problem tells us nothing.
And of course the Rio Grande is only part of the whole border, most of which is quite straight. I'd guess the straight parts is where they'd start the wall.
Sorry, yes, what you showed is the tiny portion, not the whole Texas border.
I'm OK with increasing LEGAL immigration. What I was saying was you don't mention what proposals are in place for dealing with the winding river. It may not be what you think.
I'll leave all that to the planners,l and pray they do it the very best possible way. Still I would expect them to do the fence along the straight border first.
