I have worked with Osage Orange. It grows around the Midwest. Indians used to make bows out of it. Farmers make fence posts of it. It will last forever. The barbed wire will give out before the posts. It is extremely hard, so I assume it would make a long lasting pipe. The color in the picture is very accurate. It will gradually turn to a darker color, but still looks good. It also goes by the name of Hedge.
Rekrap21,does it give any flavor changes as you smoke it?
