Oh, you can build the layout in sections of manageable size that attach securely to each other, and you can hang that assemblage from a ceiling. You really can. If you want it bad enough. And it doesn't have to go in circles for that to happen. As for permanency, you didn't say you were buying the garage. When you buy a house, you going to move the falling-down garage to the back yard? You can design a layout so it can form part of a larger layout when you get more space. Eventually you want to go from Point A to Point B, and you'll probably want to go through small stations X and Y. So start by going from X to Y. That will give you a place to start when the time comes to go big. Don't limit yourself, son. You can't always get what you want. But if you try sometimes (and lower your standards, and use some imagination), you just might find you get what you need.
Those of us who live on the desert or in mountainous regions of California or elsewhere have learned the worst place to build a layout is in a airy space that is all but outdoors. The dust, dirt and even sap from the trees can do a layout wrong. All I can say is best of luck.
Belated reply: I haven't forgotten anything we talked about thus far. It's in the back of my mind to go over to the PMRRC at your invite. And the construction advice is appreciated. I'm just not yet full bore back into building a layout right now or going clubbing. I'm dealing with some other essential chores at this hour of life... will get back at some point....Thanks, Mark
Hi. I wish to thank all for the solid replies. Alas, I've decided to skip this major project and build a smaller layout in a room in the apartment. So, am very sorry for the big switcheroo .. Please see my OP of yesterday, 9/24 at 4:13 PM..This is my latest and probably the more doable at this time...Mark
