(December 2009 and February 2010 issues) I climbed Kilimanjaro for the first time in 1999 and from that climb with six other DC’s (two were students at the time), Terry Weyman mentioned to us we should climb Aconcagua to help raise awareness for Prostate Cancer. His father has passed away from the disease and after seeing Expedition Inspiration, a show about a group of women with breast cancer who had climbed Aconcagua (the highest peak in the world outside the Himalayas – 22,840 feet), we began our yearly climb for prostate cancer. It is great to see that Ryan made it to Kili. I can relate to his day-by-day description, except he really needs to tell every one that the dust he describes gets into every part on your body, in your clothes, in and on your camera with nothing escaping. The idea is to be in the front of the line as you ascend and wear a bandana and protect your gear, especially your cam- era. Congratulations on a great article and to Ryan.
