I live in the Wasatch unit and have hunted it several times for deer but have never drawn that elk tag. A few years ago I would have told you to hold out at least a few days for a 350" bull but they've doubled the number of tags over the past five years. I still think you can do a little better a than 320" if you hunt hard. If your guide has horses I'd go into the top of American Fork Canyon or maybe up Hobble Creek. It's a huge unit and you'll see a ton of elk.
