To those folks who gave us suggestions, we thank you. We summited on July 22! It was definitely not easy, and a very long day. To those who haven't hiked up Mount Whitney yet, please know that it is doable. If you don't have issues with altitude sickness, I think you'll be just fine. I was quite nervous about those 99 switchbacks I kept reading about, but felt they weren't that bad once I was on them. My husband and I are by no means athletes, but we managed to summit. I just wanted to give some encouragement and wish you all luck! Cindy
