One of the guys who walked up Mt. Sinai with me. Chris was a life-saver. He kep on telling "Just another few miles" as he walked with me at the rear of the group walking up the mountain. I believe he was an Aussie or a Kiwi who had just finished his graduate studies and was going to London for a job. I think he said it was going to take him 6 months to get there. Long walk.
