Went after a few geocaches tonight, one at a boarded-up drive-thru out near the airport. There was a state trooper parked just across the way, and when I got out and commenced to hunting, he turned a curious eye my way. So I put on my best drive-thru inspector's face, and it seemed to do the trick. The drive-thru inspector in my trunk is a little miffed about not having his face, but we do what we must.
