I'm always seeing these cars and trucks with "Mile 0" decoractive plates on them.
Actually, I'm always seeing VigilanteGirl's car and yesterday I saw some dude's truck with "Mile 0" decorative plates.
The plate on the dude's truck cleared up the mystery for me.
Under the "Mile 0" it said in small print "Key West, Florida."
So now I know what these plates mean and I can finally get some sleep.
