John,
Oh please don't worry about when you get back to me! There are all too many things that take priority for all of us.
Head start or stalled for a dozen years now picking back up? I found my last hand drawn plan and written description for my HO layout that never got beyond bench work. I will have to fiddle with it to scan and show everyone. Basically it was Blackwater Canyon then over the top and down the Horth Branch of the Potomac, with branches to Mt Storm Power Station and Mines at Vindex Maryland. It was still too much for a bigger room in HO.
