I use to live in Mission TX, about a half mile from the Rio Grande River. A group of us guys would go down to the palapa Thursday afternoons and have a few cold ones while BSing and watch the Texas DPS and Border Patrol boats run up and down, some choppers also. You should see those rigs! With 300HP on the smaller ones and 900HP on the DPS boats...complete with 2-3 machine guns on mounts! Most of the time they would just wave as they went by, but once in a blue moon one would pull in and talk to us. Man...they had some good stories!
