Do not pass up any legal bull. I've seen a grand total of 1 legal bull in two trips with a total of 14 days in the mountains. I am definitely in the early stages of learning. Few big things that I don't know if has been mentioned or not:

Get up every morning and hunt. You will be tired, and it will be easy to snooze the alarm. Don't.

Do not leave early because it is day 5 and you haven't seen anything. That one legal bull I saw is the one in my avatar, and it was mid morning on the last day of the season.

Whenever you are planning your hunt on OnX/Google Earth, if you figure you can get to X glassing spot in X amount of minutes, double that time. I.E., my first planned glassing spot last year was 9/10 of a mile from camp. An hour of hiking time to get there before legal light is plenty right? Wrong. A little over 2 hours later we sat down on our kicked asses.
