Re: Question about the term "double heading"

This doesn't answer your question, but reminds me of a great story.
Years ago, there was an old engineer in Alamosa who was thinking about retirement and decided he wanted to try his hand at farming.
He went out with a local realtor to see a place that was up for sale. The realtor asked if he knew anything about farming and the old railroader said he didn't and they spent the next half hour or so checking things out.
As the realtor droned on about the house and the outbuildings, the engineer, looking out a window said, "Hold the phone. I ain't buyin this place."
The realtor asked why, and the old man said, "The ground is too hard."
The realtor, puzzled, looked out the window and saw nothing but a couple of hogs making time in a pen outside. He turned to the old man and said, "I thought you said you didn't know anything about farming. How could you possibly know the ground is too hard?"
The engineer looked out at the pen and said, "I don't know nothing about farming, but I know the ground is too damn hard if the hogs have to doublehead to root!"
(Apologies to Woody Woodward, I hope I told this well enough!)
