I live in the Sacramento, California area, and have been to all the Home Depot’s and Lowe’s (also Ace hardware) for 50 miles around. I can’t find anyone that has pink or blue foam in 4x8 sheets. They only carry the white beaded styrofoam sheets. I’ve looked in most of the construction sites in my area as well to no avail. I’ve called the manufactures, but they were not any help. Does anyone know where I can obtain a couple of sheets for a small layout? :?
