Most by-standers are curious and some excited about the drone. A very few have been concerned and one suggested it should be shot out of the sky. Admittedly, that's a time to hold back feelings. I asked that person "Have you ever seen a drone before"? Then I say I'm a photographer and show him still and video images of places I've photographed (see www.schundlerphoto.com). At that point most settle down and ask with interest and curiosity "What are you photographing now?" I've only met one person who I had to write off as a lost cause. In that case, it was a good time to wrap up and go somewhere else. Life is too short then of but heads with this type of person.
