While many of the interior scenes from "House of Cards" have been shot at the show's Harford County sound stages, dozens of other scenes have been shot elsewhere in Harford.
As the show developed through its second and third seasons, the number of outdoor locations in Harford also appears to have grown.
What's being shown from Harford in Season 4? We'll all know Friday when Netflix releases all the episodes.
