Jim Doyle and I decided to accept silent observers for the workshop on Saturday. We will ask 50 US$ for just listening and watching.
Regarding the price for the workshop: One has to understand that we are dealing with material that typically costs around one grand or much more. There are way too many folks out there who have lost such trees because they did not know how to treat them properly. So 150 bucks for a workshop to learn how to not loose more than a grand should be fair.
Regarding the fact that people will pay for helping doing my work. Well, it is not exactly so, but there is some truth in this. So why will almost all participants of last year be there again? I think it is because they have learned a lot and it was fun.
