Hey Paulo, I lived in Calacoto just across the river or what passed for a river back then, up the street from where the President at the time had a house. I went to ACS, the American Cooperative School for a year before coming back to the states for college. Didn't do any climbing back then but could see Illimani off in the distance.

If you are looking at the PNW and want to go light, you might think of a design like this one-

As an aside, if you go to her About page and read the Hiking in Finland interview and the comments, they are quite entertaining. This tent is a redesign of the defunct Wanderlust Nomad and a few people are upset about that.
