realitycheck, I recommend good boots. I like Lowas, but that's just personal preference.

As has been said, it doesn't matter how good a shape you think you're in. The elk and mountains humble me every time I go out.

I walk too much and I don't glass enough. I need to glass more, and you might consider some good binos.

Otherwise just spend a bunch of time out there at all times of year. You'll learn a lot. And enjoy yourself! Elk country is beautiful.
