Heck man, you think INS is just in the SW of our nation? Who do you think is on our borders all the way around? They do more than just bust illegals and check cars and truck at ports of entry, they also check ships arriving at the Great Lakes, etc... Of course they are like the military though, they say go south, you gotta go, but hey, at least they pay for the move.
You being up north, the person that posted is correct, Forestry Dept. might be pretty cool too.
