As a deer was coming up the trail I needed to stand to get in position. She was about fifty yards away in heavy foilage so I was quite shocked when she picked out a slight movement of my left leg. She turned and bolted but to my surprise she circled around me and came in to investigate. She came right up in front of my stand and stuck her head up in the air looking at me and trying to wind me. After several minutes she decided I was no risk and walked away. It was right at last light and I am wondering if asat is vulnerable in low light conditions due to the light colors in it?..............dabow
