Great looking layout, Lee. Thanks for sharing your work and your memories.
I'm amazed that you have used only two switches in all of that sprawling layout! I'm slowly amassing what I need in HO to create an "around the walls" layout with an urban switching theme within a room only 9'6" x 12"9" (plus a 2' x 9' 6" closet)... and my track plan has already used around 50 switches!!!
Anyway, good work!
