Well, it lasted long enough to be the "next guy's" problem - just sucks when your that guy!
Orangeburg - so that's what that stuff is. That's a staple of MA. Every single underground pipe I've ever seen on private property around here has been made of that stuff. Used to find it in the woods all the time and shoot it full of holes.
Always wondered what the hell it was made out of. Looks like some strange paper or cardboard layered and coated with tar. Never knew what they called it - that's the first time I've heard that name.
Looks like one hell of a job there Richard. I'd be swearing up a storm for sure on that one!
