Recently while camped up at Lake Durant a large and noisy drone flew over our site on two separate occasions, it was quite intrusive and the second pass over resulted in one of our group heading down the woods road to find the operator, while another guy shouted general threats in the direction it headed off to...me, I contemplated a pro quality target slingshot I owned years ago for it's possible future usage...
Drones are interesting tech, but the operators need to be aware of the intrusiveness, noise levels, snooping that folks on the ground would be experiencing. I can see a noisy and contentious drone tech thread developing here between adherents and old crabby Luddites like me.
