By the amount of flying done in National Parks and then posted on YT. My wife and are going out to Vegas in October and I want to take a day trip to Death Valley. For the heck of it I went to YT and did a search for "Drone flying in National Parks" or something like that. I was shocked at the amount of videos posted from flying in National Parks in the last year, last couple months. Looks like a lot of people just don't care
