Not a lot to add as so many have given great advice already. Only thing is I have really fallen in love with the radio/GPS units that will show you where the others talking to you over the radio are. It is a real safety feature in rough, unknown country.

As far as boots go, break them in before you go, and trust me running 5 miles a day in Indiana is not equivalent to walking all day at elevation. Running with a load has been the best training that I have done to prepare and I am still out of breath out there.

I do not carry a day pack, just a camel back. Everything else is in my pockets. I like it light so I can get around easier and slip through the oak brush. However, I can go all day without eating and in all fairness I am the only person I know who does that.

The terrain does vary greatly depending where you are. Where we go one part is steep, one part is rolling, one part is flat.

Calls are an option, but where I hunt they don't respond well to calling more often then not. Caveat that with the fact that the area is relatively heavily hunted. A great call that is easy to use is the Hoochie-mamma thing from Primos. No learning curve, and we have called in a few bulls with it.

Enjoy yourself. Truly, any elk with a bow is a trophy. Listen and get ahead of them and you will be set. Watch the terrain to try to look ahead of them for funnels, etc. Like anything, they generally take the path of least resistence, but if you spook them they can run miles... literally.
