Really looking forward to the class next month after lurking for four or five years. The members can correct me if I'm wrong, but I understand the vast majority of the class is instruction in building the shell of the house, getting your house under roof.. But the detailed information on electrical, heating/cooling, plumbing, etc., is all on the member's side. And through years of trial and error and mistakes by all involved, best solutions are available, with questions answered by folks that have been there and done that. What a great resource.
