Damn Sand Man, that is a hell of a bird. Your dad is a little hard headed I take it.
A couple years ago I seen one beside the road that had been hit so I stopped to check it out. It was stomping on that 2" mark. Someone had already took the beard but I bet it was a good one. It was a toad of a bird so I grab for the fishing scales out of the truck and he pulled just a hair over 29#
If I can ever break 1.5" I'll write the check for the wall
