My grandfather called them galluses. That's the term I use simply to be annoying.
And the mystery of my neighbors' Giant Pile o' Rocks is solved. Workers arrived last Friday (and Saturday) and built a fairy tale stone wishing well, with a protruding lip and a shingled roof. It's right next to the diorama of Papa Smurf shooting craps with Daisy Duke at Casino Night in a scale model VFW hall.
P.S. I made up the part about Papa Smurf.
Of course ... it's really Boss Hogg.
Maybe the well will become a pilgrimage site, and you can charge for parking on your lawn and also sell refreshments and tchochkes.
I know a guy named Smurfit, he says his wife gets some very strange looks whenever she needs to give her last name...
