Skip the guide and head for the biggest archery only hunting area in the world, the Dalton hwy controlled use area. Go after September 1st if you fail to put a stalk on a Bou there are about 10 million geese and ducks to chase. Moose and black bear are also fair game on the drive up from Fairbanks for non residents, residents can add Dall sheep and Brown bear. The haul road is my favorite place on earth but not at all forgiving so be prepared. Don't forget a fly rod the streams along the haul road are some of the best road access fishing for char and grayling in the state of Alaska. If you go with a group don't be the first to harvest a Bull. Be the second, Bou are so curious when you stop to field dress your buddies critter they will come see why you stopped chasing them. I once stopped to help a friend field dress his Bou, when we looked up from our task there were 2 bulls and a cow watching us from about 10 yards!
Because there is nothing to provide cover on the slope act like you could care less about the caribou, stalk a ptarmigan or duck near the bull you want. If your acting like your chasing something else curiosity will hold that Bou in place act like he's dinner and he'll turn into a ghost.
