Got Crevasse Rescue Skills???

My guess is Darryl would quit if we did more that one a year 

I wouldn't quit.  I would make someone else be the course organizer.

We do conduct a different course in Aug for the graduates and instructors of the Glacier Skiing/Snowboarding and Crevasse Rescue course. 

It's called Glacier Route Finding and Adaptive Crevasse Rescue .  It's described at the bottom of the web page.
