I recently discovered that my town has a yard that they bring all the trees removed from public land. The lumber is free to anyone willing to haul it off. So I was scouting around and saw some nice stuff, but was having a time identifying some of it just by the bark and a cut end. I am not an arborist by any means and have look at several websites as you suggested below, but still feel like I don't know what i'm looking at beside some of the more common hardwoods (white oak, red oak). Does anyone have any tips?
