Laws and 'rules' such as this are made to compensate for the worst cases, which generally are very stupid, inconsiderate and oblivious people, of which there are way too many. Stupidity is a rampant epidemic that is validated by today's political environment. I'll guess that most participants on this forum are generally somewhat intelligent and responsible drone operators. Unfortunately, as in every endeavor, the idiots and assholes must be reigned in by laws that, sadly, everyone must abide by. A horrible example is the no drone rule in the Glen Canyon National Recreation Area, a large swath of southern Utah with spectacular scenery. 95% of it is remote lands, with hardly any roads or people. But because Lake Powell is contained within and is a popular place to visit and vacation, the entire rec area is no drone. Terrible shame for those of us seeking grand landscape flying opportunities where drone use would not create any problems for anyone.
Someone here stated that visitors should have a drone free experience. Really? Why would drones be considered annoying when endless families of screaming children, beer swilling partying youth blasting loud music and laughing and yelling at all hours, car and truck engines running and driving around campgrounds all day and night, and barbecues and campfires spewing smoke and stink in my face are not considered a nuisance? I generally have not been able to stay peacefully in a campground for over thirty years. It's not the laws that originate the restrictions, it is the stupid and ignorant.
