I've accepted that we kind of lost the net to the money people and bureaucrats. Mid-late 90's it really was a frontier full of adventurous nerds.

There's a lot of experimentation and improvisation once you get into things like ski mountaineering because something always goes wrong. The camaraderie is also strong.
