Dang, I wonder what would make one that big?
My only guess is a short piece of rebar or something like that. It certainly wasn't there when I left the house. I ran over whatever it was somewhere on Loop 67 around Cleburne. I ran out of plugs trying to figure out a way to get it to hold air.
I didn't see anything that big in the road but my attention was preoccupied by an F150 that couldn't decide how fast he wanted to go and was doing typical cager things.
