Killian Thanks Nice remark from a fellow vet. (that name Casey was tagged on me in the Navy).
Thanks all you folks for your remarks.
Now : The rubber roof material. Rubber roofing is a roofing system that has been around for about 20-25 years that I know of. It is available from roofing supply houses. I have found many uses for this material. I purchased this last batch which is made by Johns Manville from Bradco Supply in Allentown, Pa. It comes in 15 Ft. wide rolls. It is about 1/16" thick and yes that is what is on my layout. It is nice to work with, I lay out the pattern I want and then cut it with a large scissors. I also have it on the layout I made about 7-8 years ago, it will last forever. I clean the rubber using alcohol or other solvents to remove the slippery powder on it and then I am able to apply pinstripe tape anywhere I want to make road layouts, as you can see. Some large supply house might not cut it off the roll for you and then you will have to deal with a roofer that has a full roll. There are Bradco Supplys in many states and this recent purchase about 3 months ago cost 65 cents a square ft. It is amazing how quiet my trains are using Atlas track, on this rubber my other layout has Fastrack and is a little bit louder. I also use this material for making liners for all my tool box drawers, it works great. Hope this helps you folks, any other questions, feel free to ask.
Here is a different photo before the tree, notice I made a change on the layout and had to add a piece of the rubber back. Regards, Casey.
