Police Visit

Last week I got some visitors. I was working inside the container at the time when I heard a car drive up and honk. They were two State police officers. They wanted to know if I lived there. They said that they had been by many times before but no one was there. I told them "I am camping here,-is that ok?" and showed them my ID. They said "sure" and left. I am not too sure of what to make of this, but at least I am reassured that someone has been "watching" the place, and especially that I am "not afowl" of the law.
