I dont know anything about the Vernon unit, but I have drawn tags in the Book Cliffs in 2002 and 2005. I love to hunt out there. There are plenty of deer and you will see hundreds of bucks. It will be difficult to shoot anything over 27", but they ARE out there. There is lots of different types of terrain to hunt, whether it be in aspen trees, junipers, high pine, or lowland sage. Anytime you get out of the truck and walk a couple hundred yards you will be all alone. Good luck on whatever you choose!
