RE: To hunt sign, or not to hunt sign, this is the question.
Like Buckeye stated.. it's hit or miss. Always use the terrain!
But if you use a little common sense when hunting sign you are already that much a better hunter. What I mean is this..
1. I find a scrape or two and a couple rubs coming from a really thick bedding area within 60-100 yards/ and it follows a saddle that allows deer to sneak through some open woods without being seen.. HUNT IT.
2. If I find 4 or 6 or 8 rubs and a good sized scrape on the edge of a field that you know the deer don't visit til after dark. They're simply bedded to far away. DON'T HUNT IT. But use it as a puzzle piece.
I don't hunt sign.. but I use it to determine movements of deer. I hunt topography and funnels. But I will hunt good sign within topography or funnels.
