Got an e-mail from a friend today informing me of this seemingly worthy event: Tug and Barge Quadricentennial Legacy Tour at Hudson River Park in NYC. I froze when I read the phrase "barge tours." Coincidentally, this is taking place just a couple of blocks from my home.
Also, "quadricentennial" really reminded me of "mayubinatorial."
