...decided not to. I went instead to Home Depot to get some foam, and then went to the local hobby store to get Woodland Scenics risers, inclines, ballast, glue, tacks, etc. I bought the N scale Smokey Hollow Junction track pack, and plan on making my own layout, with roughly the same track plan, maybe with a few minor differences. I can then add a trucking industry like originally planned.
By making my own layout, I saved roughly $200.
