It's funny. On Saturday I was hunting with my brother in law and heard a lot of snorting. I knew it wasn't me because I was down wind and there were a lot of trees between me and the snorting. I thought maybe it was my brother in law, but he said that the snorting was upwind from him. The biggest doe that I've ever seen walked out under my brother in law's stand right after that and he shot her. Apparently, she wasn't spooked.

Yesterday, I watched a small buck for about thirty minutes in front of my stand. He walked away and I heard a couple of snorts. He wasn't spooked. I saw him on and off walking through the area for the next two hours. I think some of the snorting is communicating or being startled at something... and it may not be you.
