Hello, my wife drew a caribou tag along the western half of the Denali highway. I have never hunted caribou up there before. I have hunted caribou in the western Alaska Range, the mulchatna herd over by Illiamna, and along the Dalton Highway. My question to anyone willing to offer some advice is how essential is an ATV for hunting the Denali highway? I have never done much hunting using 4 wheelers. I mostly like to travel by foot or get dropped off somewhere by aircraft. My wife and I don't own a 4 wheeler. I have considered getting one for this hunt and for bear baiting, but I don't currently own one. Thank you in advance for any advice anyone has to offer.
