If you want awesome grouse hunting definitely go west of Sundre and Caroline. Pretty much anything west of Trunk 734 is Crown but if you just look at the map they provide you with in the huntin regs you can see a green boarder line and anything west of that is crown, now there is tons of well roads and cutblocks and cutlines you can hunt, i see TONS of them just off the dirt roads sittin inside the trees. When im hunting for deer out there i usually bag a few driving to different spots i hunt deer, so just drive around and keep an eye out or just walk the cutlines and cut blocks and you should have not problem filling your limit.

As for west of Longview i hunt nothing but private land there and my family are the only people the rancher really lets on but we hunt that land for big game but if i see the odd grouse i shoot them with a survival gun i pack around(holds one .410 shell and one .22 bullet)
