Thanks to everyone so far for the advice - it's great. I've read just about everything posted on this site (First timers, what can go wrong, etc.) and I read the trip reports daily. Trail Runner - I read your story and love that you made such a great memory with your son! I love all the stories and pictures - truly hope I'm in one of them! I've actually been planning this since January and have upped my cardio significantly. My biggest hurdles for this trip are altitude, weather and hydration/nutrition as I tend to loose my appetite when exerting myself. We plan to go pretty slow though.
