Karin, great TR and excellent photos! It sounds like you had a superb time and definitely got your friend hooked on the best of all possible hobbies. And speaking of the transformative powers of the mountains, you're a classic case yourself. Could you have believed 3 years ago that you'd have this backpack under your belt, along with mutiple Whitney summits, Shasta, and Kili?! You'll be chasing Laura down before you know it!
Maybe it's time to jump in to a day or two of the Sierra Challenge?
