a while back i had opportunity to visit Todds trains north of raleigh (3hr plus drive). He had some sheets of plastic used in scratch building buildings, some pieces to scale grooved as in siding, some that could be used as metal roofing. I bought some to play with at home, and came home and put them in safe place, so safe even i can not find them. (5 yrs from now i will find them)
all you guys out there probably know just what i am talking about and could point me to web page. nearest town for me that has any model railroad is Raleigh NC and it is quite a drive to just look around
