Bob - You didn't say what area of the country you're from. In some areas it seems the extruded pink or blue foam is kind of hard to find, especially in the thicker sizes -- something to do with the climate and the popularity of basements, I think. If the folks at Menards or wherever look at you like you're nuts, keep looking around. To answer another posters question, you probably need to use adhesive for everything, nails won't hold in foam! Glue the road bed to the foam, glue the track to the roadbed. The trick is to use something that will let you correct your "misteaks" later without doing too much damage. Regular white glue (not water resistant) works for me, you can get it wet to make it let go. Another thing to watch out for with foam is to not use materials (adhesives, paints) that attack the foam. Liquid Nails is another popular adhesive, but there are several varieties, some of which will dissolve the foam. Solvent-based paints are another no-no. Finally (deep sign of relief) make sure its the dense foam, not the white beaded stuff. That kind has very little strength, and cutting or shaping it makes the place look like your bean bag chair exploded. The pink or blue kind makes a mess, too, but not as bad. BillK
