In March 2008, to celebrate my 42nd birthday, I attempted a winter ascent of Mount Washington, NH (6,288 feet). Unfortunately, we were stopped at the Lakes of the Clouds Hut by brutal weather: strong winds (85+ mph) and COLD (-49 degrees F); it was worse up top!
The day before, we had summited both Mount Welch (2,605 feet) and Mount Dickey (2,734 feet)to warm up, learn skills, and gel as a group.
I have to give the highest recommendation to Mooney Mountain Guides, who educated us and led us up the mountain, and were brave enough to turn us around before the summit due to the dangerous conditions, even though we all wanted to make the attempt.
[Pushing limits is fun, though sometimes it takes years, like jumping out of a perfectly good airplane.]
