This is pathetic. In all of my time at any one National or State park I have run in to more annoying and loud tourists than I would have liked to and to consider a drone that is in the air for all of about 25 minutes and certainly not all in one place, being annoying is just stupid. The key word to this is that it is a PARK and a park is where you are supposed to be able to fly your kite, play frisbee or fly your drone!
