RE: How often do you NOT see deer?
I see deer probably a bit over 60% of the days I am out. Last year I saw my first deer on the fifth and last day late in the day. That was unusual. I had about a two second window while the deer had paused to leap up a bank. At 65 yards, quartering away offhand, I hit right where I aimed and put her in the freezer.
I think I have had years where I saw no deer but I cannot recall for sure. I go hunting for the hunt and not necessarily for the kill that is the object of the hunt.
