Concrete is the most wonderful thing. It can be troweled on and then carved into anything imaginable. Today we went all out to cover as much of the tree as we could. We mixed and troweled on about three cubic yards of concrete mud. We let the magic mix set just enough so that our carving tools didn't pull it off the galvanized mesh. We then set about making it look like a gnarly old tree. Once painted, few will believe it is concrete. A ride operator's booth never looked so fun!
