Hunt the funnels.
Always hunt the funnels if they are available. All the "pros" will agree. It's the best spot to see a concentration of deer as the funnel is the easiest path for the deer to take.
For what it's worth...I think the only thing that rubs or scrapes mean is that there was a buck there at one time. I believe that if a buck is walking by and see's a tree and just feels like making a rub or scrape he will. I don't believe they will intentionally visit that spot again. The only exception being when there is a line of rubs or scrapes along a ridge or trail. Then the chances of the buck returning to visit that tree again increases.
G/L with whatever stand site you choose. And please post the pictures of your kill.
"The sportsman lives his life vicariously. For he secretly yearns to have lived before, in a simpler time. A time when his love for the land, water, fish and wildlife would be more than just part of his life. It would be his state of mind." Author, Jim Slinsky
