An outhouse in the middle of a road

I think I messed up by not doing a photo essay on the new gas line they're building from Canada to Texas. There's been stacks of these pipes arranged in a nearby field for months. And the completed line is only 10 minutes from our house.

While I was there, I kept hearing a banging noise from inside of the pipe. In the middle of nowhere, with such a foreign contraption as this, the repetitive noise, which I still don't know what it was, instigated a couple of cowardly screams as I was caught off guard by the shrill echoing effect of whatever caused it.
