It's all very exciting. And as my most-planned and highest elevation personal trip to date, I am banking on a good outcome.
When I was living in La Paz, Bolivia, I decided to attempt Huayna Potosi (6088m) with two friends I had met in South America, John and Chris (New Zealand Chris). We planned in 2 days, taxi-ed up to the base of the mountain, and proceeded. Roughly 200m shy of the summit, we decided to turn around; as the only one of our team with any climbing experience, I was feeling the effects of both the altitude, a lack of sleep, a poor course of food and a month-long binge recovery.. It all seems very foolish now.
This time, we are prepared, our plan is watertight, and our team is a lot stronger, both physically and mentally, which is necessary for a mountain of Denali's caliber. I checked the weather up there the other day.. -65C (-85F) on the summit. Can't wait.
UPDATE: We went with Jagermeister.
