first get a USFS map and see where the private land is. then get in shape, that area can be rougher than all get out. When I lived in greeley years ago I worked that area from east to west toward the park. I saw plenty of animals but if i had shot I would have needed a mule to pack them out. a good topo will make it a bit easier deciding what section of that unit to hunt. if you were to get lucky and ever draw a sheep tag for that unit, west of drake would be the cat's meow. good luck!
