During a recent flight from Washington Dulles (IAD) to San Francisco, we flew over Yosemite National Park, and were dismayed to see how much smoke and fire are covering this national park. It really is disturbing to think a CARELESS camper could create so much destruction by not following the "no burn" rules during such a critical time. The fire seems to be burning with no regard to where it goes. I just hope it's snuffed out soon..............
