My Son and I drew 3rd season deer tag. Looking for a little help. Of the 3 units which is the one to concentrate on? What is a good map to purchase and where can I get it? I do have OnX for my GPS, but like to study paper map. Also would like to know where to focus our attention. What can we expect for deer density? Is there a possibility of seeing a 160 buck? Thank you for any help.
