12:59 PM
Taj Mahal just came up in my Winamp playlist singing "She Caught the Katy":

She caught the Katy, and left me a mule to ride.
She caught the Katy, and left me a mule to ride.
My baby caught the Katy, left me a mule to ride.
The train pulled out, I swung on behind.
Crazy 'bout her, that hardheaded woman of mine.

So my question of the moment: what is the "Katy"? Just a few minutes with Google turns up the answer:

"Katy, or KT, stands for Kansan and Texas Railroad (K&T)."

More on the Katy can be found on the official site of the Katy Railroad Historical Society.
