Down for the day. Anyone waiting in the line on the main road of Breezy waiting for a token to get through the gate. Anyone who goes to the beach with shoes and black socks on. Anyone who has to stop and ask directions to Kennedy's. Anyone who parks in a sand lane. Anyone who thinks that Security is really the Police. Anyone who needs a map to get from The Sugar Bowl to The Blarney.
That guy is definately DFD, he's carrying his cooler instead of using a wagon.
