Thanks for the response Ray.
I have decided to use the rubber roadbed and will begin to clean the supply I bought shortly. I thought that I would use the double sided carpet tape but, based on your experience, I may use hot glue - I love that stuff.
Work on my small Flyer alcove layout will begin in a week or so, as soon as I finish some work I started on Warrenville. I have already designed decals and finalized my plan for a 1950's type store display for above the Flyer layout.
I'm looking forward to sharing pics here of my Flyer alcove layout and display within a month.
