Yes, coues deer hunting in Arizona. Hiked two hours in the dark to set up on a rough canyon with the only water I knew of for miles in a trough at the base of the cliff coming out of a seep. As the sun came up I saw a tent set up directly below me about 100yards away from it and a pop up camo ground blind about 15yards from the water hole. About a minute later I picked up the flash of binoculars looking back at me across the canyon on the skyline. Turned to leave and passed a guy hiking in the trail I was going down. This was about 12 years ago and google earth was just getting popular as a way to scout and I later discovered that my hidden little secret spot was the only green dot in the desert if you looked on line. That was the first time I had even seen another hunter in that canyon in three seasons.
