Fairfield County, Connecticut. Fabled as rich and extravagent, but mostly mediocre. Some towns are home to areas that do fit the common description of 'the FC': Conyers farms in Greenwich, Smith and Oenoke Ridge in New Canaan, and bits of coastal Darien, Westport, and Fairfield (Southport).
"Man, I heard everyone in the FC has their own plane! Money grows on trees there!"
"Nah yo, ever seen Norwalk, Ridgefield, or Stamford? That's what I thought!"
