I wonder if they could put some kind of barrier in the Rio Grand that would prevent boats from crossing and make walking/swimming more difficult? I figure try it in a few popular crossings, see if it redirects them, then easier to make a boat convoy/blockade.
Of course I know nothing and am just thinking out of my arse.
Release the gators!

Alligators?
