A friend and I visited the San Rafael Swell, Ut last week and had an incredible 4 pack of adventures, some hiking and some roped climbing and rappelling. This day we hiked some rough terrain up to the mid point of the Swell and traversed to an incredible set of arches towering over a deep box canyon with a free hanging rappel. Let me tell you, flying a drone in a deep box canyon if fraught with danger and risk, minimal GPS signals wall on walls across 270 degrees! Despite it all, I was very please how this baby came out! I was bummed about how at one point my focus went bad, I always simply run it in auto mode, any ideas???
