The first time I went deer hunting as a teenager with my father, uncle and grandfather, we had literally scored the one and only camp site within a 10 mile radius outside of this small hunting town in CO. We had gotten there the friday before opening day and the site itself was the only one in about 20sq miles that had adequate trees for hanging game. It was surrounded by rolling hills of sage brush and prairie grass with only one entrance to the south that went over a hill and into an abandoned town. Around sunset we had finished setting up camp and everyone else decided to take a nap. While they were doing so, I decided to take out the binos and glass around for a bit.
I went off walking for about 30 minutes and had made a surveillance around camp-glassing in all directions. When I got back to camp, I noticed that there were a couple trucks on the ridge where the road heads back towards town, at about a mile away. Being a curious adolescent, I raised my binos to find that there was a man looking back at me through a pair of binoculars. At first I didn't think much of it and just went about my business about camp. About 15-20 minutes later, I had happened to look in the direction of the vehicles and noticed that they were still there on the horizon.
So, I picked up my binos and glassed over to them and what did I find? Yet again the man was still surveying our campsite. Well, this didn't feel right and I ended up waking up my father and explained the situation to him. He dismissed it after looking over at the distant cars and seeing them leave.
Well...later that night, well after dinner and after we had hit the sack, I was awoken by the sound of a truck's engine and the whiteness of someone's head lights shining on our camper. After what felt like eternity, the trucks turned around and left, but needless to say the experience left a weird sense of paranoia with me throughout the hunt.
