Define "not normally of interest".
I've been sitting somewhere happily photographing birds and had rentacops come up and ask what I was doing, they didn't even know the birds were there. I've also been seen on my belly under a bush photographing a bug or lizard. I suppose that isn't "normally of interest" for most cops, but it's what I do!
One of these days I'm going to shove a monopod somewhere the sun don't shine, I'm tired of being messed with!
