Hey everybody, I am counting on your combined experiences to help me out here. I want to build a track with realistic scenery for my DigiQs, The cars are actually Super Deformed, That is what is causing me to freak out. What scale scenery is best suited to these? And does anyone have any details on how to make realistic landscapes(hills,rocks,tunnels)? I know they can be made of "Spray Foam??", Can anyone give me more details on what this is and how to use it, Also my experience with styrofoam has shown if you spray it with paint it desolves, So how do you paint it? I need all the info I can get on this.If I were to use model train scenery and such, Which scale do I use, Please be specific and list it by size (1/XX) and (HO, N, T, ect.) I only intend to spend about $150 so give me cheap But high quality ideas. I know I can count on you guys!

Thanks in advance for your help!
