Hello Mike, I got the full scoop on it now. The pipe is on top of the 25' wide driveway, Somebody put one of those "Bolt On Speed Bumps" (it is hollow on the bottom) over it to protect it in that area, The rest is buried about 3"-4" in the spots where is is buried at all, Some of it is run on top of the ground under the mulch/pine straw in the flower beds.. All told it is about 90 feet in/on/over the ground. I'm thinking directional bore with the yellow plastic pipe they use for gas lines pulled into the bore.
