In a Rest Area at night there are always a number of things going on.
Some drivers are parked and trying to sleep.
Some drivers are entering or leaving the Rest Area.
Some idiots are out wandering around taking pictures. ;-)
(I'd add this photo to my map, but for the life of me I can't recall where I shot it.)
Shot on Kodak EliteChrome 160 Tungsten (expired 2003)
