I climbed Mount McKinley in 2013. My partner was 78 years old at the time and had recently had a hip replacement. I wrote a trip report about our climb for the Mountaineering Club of Alaska's newsletter, the Scree. If you're interested in our logistics and how our trip went, send me your email address and I'll forward you a pdf copy. Alternatively, you can find the trip report in the October 2014 Scree on the Mountaineering Club of Alaska's website athttp://www.mtnclubak.org/.
MCA membership ($20 per year for individuals) is required to view the Screes online.
