13B is a very large unit. If you don't know where the deer are then you'd better find somebody that does. I drew an archery tag and thought about doing it myself as well. I talked to several people that had hunted the unit in the past. They all said the same thing, get somebody that knows the unit. I called several outfitters and I eventually booked with Brec Bundy and MDA Outfitters. They guided me to a 222" monster which I took down on the 6th day of the hunt. You can definitely diy but your chances of a trophy success just aren't very good. Good Luck.
