The layout is down, and in one box in preparation for a move downstairs to my (planned temporary) "man cave", a finished room in the basement almost 12x20, heat and air, mini-fridge. I will be reconstructing the 5x12 layout as two 5x6 modules, on 2" thick foam sheets on a 2x2 frame.
The layout will rest on this dining room table I made 25 years ago for an 'N' gauge layout inside. The three tops remove, and the sides can fold down on piano hinges. Nothing in there at present. Very strong and stable, rolls extremely well, and has held up well over the years.
