Clem, same here. I had corn up to the edge of the woods I was hunting. Got down as I could hardly see the green fiber optic front sight and it was no longer legal hunting time. As I passed the last row of corn and entered the harvest soybean field there were 3 nice size does browsing. Legally it was too late to shoot, and they were way too far away. I tried to put the sight on them but I could just barely see a little glow and that was it. However, I did try to see how close I could sneak upon them. But it was useless, but it was nice at least to see a deer. Next time as dusk approaches I'm going to remove the rear aperture and use it as a Ghost sight.
