You can rent horses from Sombrero Ranch, I hear you have to hold on real tight! I've killed most of my elk and mule deer in Units 12 and 13 with an outfitter. I've seen as many as 600 elk at a time, the private land is surrounded by BLM and a lot of elk get pushed onto it. I killed my first elk in 1996 on 10/19 and it snowed 16" and my last elk the first week of November in 2008 and it was 70 degrees. I suggest finding some BLM that is generally hard to get into and then get as far back as you can and sit tight. Good luck!
