Hello,
That's to bad really. You have a truly different model of that sort of thing there, than in the US for example, I call it the Strasbourg model, much more controlled and limited by the professionals. I hope that the organizers will get the chance to break through the barriers at some point for the sake of folk like you and me. There is one possibility short of the whole Tour de France option though and sort of along the lines of the American example and that is the courses through Dick in Metten, De. They do have some carpentry oriented programs if that interests you at all.

With some of the steps in between:
It takes a lot considering all the double and tipple layering. The result with the sweet chestnut is a lot more lively and interesting and well, attractive compared to spruce or cedar shingles so even though I've come up a bit short I'll continue with the chestnut.
Greetings,
