Cindy, welcome. I sometimes try here to explain medical issues, but explaining WG is way out of my league. Will keep to simple stuff like AMS/HACE/HAPE.
I looked at your site. Got a kick (literally) out of your Aconcagua story. I did something similar when I jabbed my crampons into the other foots gaiters. Fell and very nearly rolled off that mountain. Congrats on the Big E. Harvey
Hi Harvey,
At least when I broke my leg it was a good story: fell on Aconcagua at 19,000 ft and had to hike down to base camp. It's a lot better then "oh, I stepped off the curb wrong"

Trying to explain Wegener's is almost impossible!
Thanks for the congrats for Everest. That's another topic that will take a book to describe.
