I have to drive to Mesa, a bat company. Only when the baseball season I full do they have it regularly. Right now a couple of months to get enough. I get est 72 cu ft to 150 gals at a time. I have a lot off it right now in bags that are falling apart. If you want 100 gal let me know, I am going to be using some of it as fill. You need to bring bags to re-bag it. I also got some from truss company's. most sell it to recycling company's, asking 3 figures and you have to take scrap wood with it in a 20'x 8'x 5' or 6' dumpster. Call around, Amy place that works with wood.
