This morning I've been on several websites that sell backgrounds for model railroads: backdropwarehouse.com, railroadbackdrops.com, realisticbackgrounds.com, tracksidescenery.com, etc. They all seem a bit pricey, especially backdrop warehouse. But I do need some mountain/hill backgrounds for two 10-foot sections of my layout. Anyone had any experience with any of these companies, or suggest another one? Thanks.
