I saw on my IG feed that John McPhee had scheduled some courses in California, so I checked out his website. Saw one within about 2 hours from me with a reasonable $425 cost; but I was mistaken. The $425 was the 50% deposit for his 2 day class.
I'm not questioning the quality of the course, the bona fides of the Sgt Major or the free market, just recovering from a bit of sticker shock. The tuition for my 2 day courses with Vogel, Haught, Stoeger and Douglas all started with a 4.
