The Pinyon Canyon Maneuver Area (military base), sits smack dab in the middle of that unit. To hunt the PCMA, you will need to go to an orientation class and they have those on the base and at Ft Carson.
The sheep are in the canyons along the Purgatorie River, and they venture out in the local rye fields (private land) to forage. You can pay $$$$ for access to the private land, or show up each day and hope they are on the PCMA or in the river bottom which is National Grassland.
If you choose to hunt the PCMA, drive to each canyon several times per day and use good optics.
Good luck to both of you!
PS I drew S04 for August!
