The last two years I've stopped using scent lures and calls. The reason I've stopped is that I seems to see more deer when I wasn't using them than when I was. So, I carry one of those doe bleat can calls, and that's all. I only use that when I see a deer. The can works great to stop a deer.
I think the people that know how to use them properly have a lot of luck using them. I think a lot of people over do it. My own reason for stopping is that I enjoy just relaxing in the woods and seeing what comes by. Hunting was becoming too much like work when I was hanging scents around and planning how I was gonna call.
