Water guys with guns (aka border patrol)

I simply wanted a glimpse of these Rio Grande guys passing by...but they pull over, a border patrol truck pulls up to my left, and I stand in a swimsuit by the border surrounded by guys with guns. . .

Blah!

Luckily my swimsuit was dry, the officer in the truck was cool with my explanation and the water guys were just taking a break for a few--whew!
