The propane line that I thought was a spur to one of the outbuildings turned out to be the main line from the tank to the house. They just took a detour the other way around a big tree and not the direct route.
I have a couple other projects that need a backhoe so gave our local operator a call and he will be out here for a day - also re-attaching a hydrant in the garden (the one I backed over with the truck in 2011) as well as bringing in a couple of yards of gravel to redo the driveway.
Fun fun fun...
