This site had me so concerned I used the H rather than the Plus. Recovery is impossible if it goes down. This is an active sink hole and there was a huge cave in just as I launched which shook the ground and a tremendous roar. Flying over it makes it appear serene but that is deceptive. Hundreds of feet under the ground is a mine that is causing the subsidence. A chain link fence that was installed to keep gawkers at a safe distance is already hanging in mid-air.
