When I was little, my mother would always play a game referred to as : "What river is this?". Each time we traveled to Deltaville, my mom would ask what river we were driving over. Whenever we would cross a bridge, I was always asked, "what river is this?" in a sing-songy way. My daughter never liked the game and once she could read, she would simply wait to answer after she was able to see the sign. My son, however, loves the game and embraces it wholeheartedly. When asked what river it is, he usually replies with "I don't know" in he same sing-song fashion as the question was asked. But surprisingly at the age of 3, he was able to come up with the names.... sort of.
The Piankatank that we travel over on our way to Mathews or Gloucester became the Piankahannock.
The Rappahannock which is the river our place is located on became the Rappahanatank.
But my all time favorite was the time we drove through West Point across the Pamunkey, that became the Pot Monkey (I've known a few of those in my time).
