170-180 Bucks are very rare, but you do have an excellent chance at a mature buck. Last year the resident success rate was 61% with 62% of those 4 points or better. For your first scouting trip, look at the areas suggested on the NDOW web site under Hunter Information Sheets. This will give you some good areas to look at, however, since these areas are traditionally hunted and well known, I'm not sure you'll find the class of buck your looking for. For the size of buck your looking for, you may want to look at less pressured areas. Is Forty-nine(sp) mountain in your area? I can't remember. This is private land near Vya, but if you can get permission to hunt there it has produced some huge deer in the past. I also agree with COSA that hunting the last week should be your best chance.
