When I was flying spotter for the Sheriff's Dept. we spent most of our time taking pictures, circling over semi truck trailers, hidden deep in the woods.

The Sheriff's Dept. got the addresses from the electric company, which would point out 'high usage' remote locations. The Sheriff told me they also look for pigs, as the growers will often set up a hog operation next to the grow houses, just so the smell will put off the search dogs.

I was always a little nervous flying so low/slow over those places, I figured we'd get shot at if we hung around too long.
