I definately agree with what
@brymoore posted. I mean you can probably get more grouse if you walk slowly, but that's about it.
A few other things I would add to this conversation is if you're coming from the eastern part of the country is to not expect to hunt the day after you arrive. You'll probably be altitude sick and the landscape will be shocking. You can see more than 100 yards which can be very overwhelming. Think sections not individual acres. You have to put miles on your boots. But exploring and not moving half the speed of smell is fun!
Another thing that may or may not have been mentioned is that if you start to smell something
delightfully putrid and musky when hiking around then it may be time to slow down for a few minutes and put those still hunting skills to use. Elk reek. Somebody may have mentioned that but it probably is worth repeating. I'm not sure if any of this applies to you, but I'm sure somebody is lurking on this thread and it may help them.
