Glad you got it back. I would have to think that made a heck of a racket and mayhem when it came off. Must not have been anyone behind you when it happened.
I'm amazed (but happy) you got it back. I thought it was gone forever. So, what was it, just sitting along the road or had they picked it up and moved it ?
I had left a message with the highway shop and later in the day got a call saying what mile it was at and that they had dragged it off the road. It was out there 26-27 hours before I got it. Stuff was in the opposite side ditch from the direction I was going so it had slid across the road.
