Yeah, I didn't know what a tinhorn was either. Regional term maybe?Gotcha. I had envisioned something upright.
That's a battle I'm about to have again, as I am about to have a gravel road graded. the culvert is set well below the road surface; yet every year he takes a little bit off the top, and a little bit more off the top... after a few years he's grading the top of the culvert off. He's an experienced operator, it seems like he should know what he's doing.
Could the culvert pipe itself be working its way upward every year with frost? Seen that happen a lot when they are only a couple feet down to begin with.
