Signs

The rest areas in Tennessee were named after musicians.  Johnny Cash had his own; all the lesser musicians had to share two or three to a rest area.

I saw some amusing roadside signs in Tennessee- those advertising "FLEA WORLD" and "LIQUOR WORLD" particularly.  On entering Texas there was an electronic sign that said "DRINK AND DRIVE".  It alternated with the message "GO TO JAIL", but on a slow cycle, so someone who was drinking, driving AND speeding could easily miss that little detail.
