I was just up to elk country the other day to see the elk. They were bugleing pretty good, and we saw some really large bulls, and about 25 elk altogether. In the core viewing areas where the elk are just about tame, you aren' t allowed to hunt them. I don' t know how the elk react outside those areas, in order to form an opion on the difficulty of the hunt.
