Malhuer River No1 Antelope

A buddy of mine (not me I only have 5points) drew a Malhuer River No1 Antelope tag this year here in Oregon. Not sure how much leg work he will do in planning-but I don't plan on spending a bunch of gas scouting areas that are worthless. Of course I will also make a phone call to the area biologist. But was wondering if anyone had hunted the unit in the past for goats and could give me a couple of points in the right direction. Not looking for anyones honey holes. If this looks familiar I also posted on Ifish and Monster Muleys-thanks for any information.
