For new guys, know your limits. There are guys out there who are like mountain goats and go up and over mountains with ease. Let whoever you go with know your limits. That doesn't mean don't try to get in hunting shape though. Go on hikes with a pack on your back, and isn't as big of a deal for us locals who are acclimated to higher elevations already. The guys I've seen struggle are from out of state at low elevations.
