I'd offer another alternative... The Book Cliffs Bitter Creek (Early) hunt. It had an 89% harvest rate last year, and I saw some of the bulls acquaintances of mine took. Definitely in that 320-340 range (one 360+). It looks like 18 points will get the job done for that tag this year. There are roads galore on the unit, and you guys will get to scout as much as you want, and hunt the way you want to hunt.
I'm not dissin on Deseret. As far as I can tell, they are one of the more friendly CWMUs in the state for the state hunters. But, you will be taken to the animals they want you to harvest. Maybe that sounds like exactly what your father needs, in which case, do it.
In fact, if you have a free day, I'd recommend you cruise up there in the next couple weeks. You will likely see herds and herds of bulls out in the open areas close to the highway out of Evanston. We've gone 2 of the past 4 years, and seen over 100 bulls each time. Head on up there this weekend and check them out. Has anyone else been this year and seen them..???
