21 is a totally migration hunt. If you go up there in the summer or early archery hunt odds are you will not find a deer in 90% of the unit. Last year the migration started late and the deer just were not down. I had planned on taking my brother in law over to the Utah side of the unit but he said that he was done hunting, luckily we found the buck that he shot on Sunday evening, so they were starting to come down out of the higher country.
I have never hunted 22 other than for rabbits 30 or so years ago. But like 21 there are a number of oil field roads in it and I don't believe that access would be a problem. If the number of vehicles going into 22 from 21 were a indication the hunting was pretty good, not sure about the finding. 22 is going to have more high country than 21 so that alone should make it better earlier. There is a member on here that hunted 22 last year so hopefully he will chime in.
