My sources have stated that there is a substantial amount of particle board available for FREE and everyone is welcome to take some of it. A warehouse full of racking was dismantled and they don't need the shelving anymore. There are thousands of sheets.
They are unpainted 24" x 48", 1/2" thick.
It can be found at 8195 Dallas Drive. Go around to the back of the building and you will see a dozen or so pallets of material lined up along the wall. Take as many as you want. Please do not leave a mess.
They should still be available 24/7 until the end of the month. Anything left over will be recycled.
