If you think that areas crawling with game now, you should've seen it when you could get pronghorn tags guaranteed on first choice, or before the deer herd had a massive die off in 08. Ive been hunting that area off and on for almost 20 years, probably won't be anymore. It's already gone way downhill in my lifetime.
On the plus side, it's still a cool area. There's paleo Indian kill sites there, and Big Nose George hid out in Rattlesnake Canyon. Unfortunately that didn't end well for the lawmen that tracked him there, but that's another story.
