I hunt Blue's in Montana and will be at it again In Sept. Montana's Grouse season opens Sept 1st. Where I hunt Blue's is a hike to get to, but good hunting, plus breath taking views.
Blues in these mountains are from about 6-8 thousand feet, the mountains peak out at 9 or a bit higher. Trees are White Park Pine and junipers, kind of open and park like. There is also some brush and plenty of small and scrub pine. Early season grasshoppers seem to be a favorite.
