You will have alot of fun on Vernon. There are a few really great bucks, alot of smaller guys, and a huge variety of in between. Dont worry to much about it, if you do what it already sounds like your ready to do, scout,scout,scout you will have a blast. There are alot of bucks up high, get off the bikes and keep wiggling and you should have have no problems finding a real nice stickable buck. 200" yes they are there, for sure not in every canyon, what you will see if you put in the time is some nice wide bucks, a few cheater bucks, some real unique bucks, and just alot of great animals that are happy to be alive and living the deer dream. Sometimes the score thing needs to be not the focus, if you harvest a buck you think is a good deer, the numbers shouldnt make him less important. Honor whatever animal you take, and love him for him and the hunt he gave you. I think your going to have a blast, I am not speculating the bucks are there. My eyeballs have processed them and the adrenaline gland has secreted over all of the above mentioned deer. Have fun, and best of luck.
