That is a very good point regarding animals being wise to ATV's. Last year I was sitting on this hill watching a couple of draws and a spring. There was a small two track road, but I had seen deer on it the day before so figure what the hay. Then these deer came running down this draw. I could hear nothing and see no reason why the deer spooked like that. Then a couple of minutes later, these two guys on ATV's came right down that draw and got to that little two track before they even saw the deer. Then they stopped and looked for maybe a few seconds and then took off again and went UP the other draw I was watching, which is where I saw the deer the morning before!! I was not sitting out in the middle of the open, but I was not exactly playing hide and seek either. They never even noticed that I was there!! Kinda made me laugh. Good thing there was nothing in that group that I could shoot, but it still torked my cookies a little bit.
