Burning Man/Black Rock Rangers had an orientation you had to attend to get permission to fly your own drone/quadrotor. I'm assuming you also had to agree to their photography policy, which I'm okay with as I don't want pictures of me riding my bicycle naked across the playa showing up on Flickr.

They probably had to also touch on the fact that many of them will be flying FPV (first-person-view) with a headset, so dealing with those if they're recorded as well (most aren't, so probably a non-issue).
