Courtesy of the city recycle area. Mostly Black Locust and some Silver Maple. I've been waiting all winter for them to come through. Found out they contract all their tree cutting now due to budget cuts and lay offs so the tree service guys aren't dumping as many trees there as the city use to. I could of had two loads but another guy came there shortly after I did so we had to share. I think I got the better end of the deal, he wanted the Maple and I said I'll take that thick bark looking stuff. lol
