trainboard foam

is there anybody here near, or in st. louis Missouri that can tell me where i can get foam to put on top of my train board, so that i can paint on it, cut it, do stuff like that, i can never seem to find it.

You might try Lowe’s. They carry various types of foam board. I’ve always used their blue three quarter inch thick type, but be sure to peel off the clear plastic covering before using.
