Apparently this was a problem that needed to be addressed. The National Park Service has announced drones are banned from all of America's 58 National Forests. Originally only Yosemite was listed, but a spokesman said the ban applies across the board.
"The park has experienced an increase in visitors using drones within park boundaries over the last few years," a Yosemite news release said. "Drones have been witnessed filming climbers ascending climbing routes, filming views above tree-tops, and filming aerial footage of the park."
Basically, the ban has been made to save visitors from a buzz kill. The report says drones ruin the experience with noise, interfere with rescue operations, and endanger wildlife.
In the off chance you own a drone, don't be that guy this summer.
