I personally have very little interest in deer hunting any more. In part because of the fact the wild deer are so small and the odds of there being one worth shooting being to slim.
I also think land access is an issue in some way for me. I have a place to hunt, but God forbid the deer cross the fence line before expiring. The deer might as well have fell off the face of the earth then.
I think the third thing for me is I grew up hunting in a group. We did deer drives and hunting had a social side to it. We always hunted with the same group and enjoyed the 9 days of rifle season. When group hunting became hard to do because of land access, and because a couple decided to start stand sitting by themselves, as well as some of the old timers that made things fun died, the group disbanded. That was the end of the social side to hunting for me.
I think those 3 issues more than anything have ruined hunting for me.
