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.
