Many, many years ago, here in Mississippi, there was a flat bed truck.On
the bed of that truck was an Electric Chair, I kid you not!

They used to drive that old truck around to whichever cities and towns
in Mississippi where they were going to Fry whichever murderer or
murderers and they used to hook the wires up to one of those electric
power poles and the Executioner guy would throw that switch,,,,
ZAPPPP!!!

You can find a photo picture of that old Electric Chair Truck on the
web.
I have seen it before.
