What a great day to be on the road! 66 and sunny and heading through the back roads, listening to the music, changing course often.  One slight caveat...I neglected to fill up the tank when I left Cape Girardeau, MO this morning...oop   Suddenly along highway 421, just over the Mississippi river bridge into Tennessee, the rover ran out of gas.  Never has this happened.  Luckily, it was a gorgeous day to sit in a Tennessee hillside, I had my AAA card, and 30 minutes later there was a rescue with a can of gas, and on the way I go.
