After reading a couple of thoughtful and very useful replies (thank you!), I realized that I had used an incorrect term. I should have used "walk through" (as Mianne uses the term) rather than "around the room" layout.
I am in my fifties, do not have flexibility or dexterity, and have no interest in "ducking" <grin>.
Due to the small size of the room (I can't believe I'm writing that, since I never imagined having this much room to run trains!) am I better off trying to convince my wife to have a ceiling layout in her sewing room (26' x 15') for the MTH Challenger, and run the smaller stuff in my train room? (Never mind on the ceiling layout in the sewing room - I just asker her, and it was vetoed. [She even made the blasphemous suggestion of selling it if its too big]).
