Viewers have been tuning into House of Cards on Netflix, and that means they've been seeing Havre de Grace undercover.

As of mid-February, Tech Crunch reported that House of Cards was the most watched show on Netflix. Much of the political drama, released exclusively on Netflix Feb. 1, was filmed in Harford County.

Specifically, Havre de Grace was used for scenes of , the hometown of the show's main character, U.S. House Majority Whip Frank Underwood, played by Kevin Spacey. House of Cards gives viewers a glimpse into the underbelly of Washington politics. In one of the series' 13 episodes, Underwood must travel from Washington to Gaffney to ensure a giant peach doesn't foil his political aspirations.

Spacey was on set in Havre de Grace when Patch spotted him at the Union Avenue opera house last June. House of Cards also filmed at a farm near Level on MD Route 155 and at two Webster Village homes on U Way.

An old Macy's distribution center in Joppa provided 300,000 square feet for creating sets to shoot scenes like the House of Congress and hotel rooms, according to IMDB.

With the production crew based out of Joppa, filming in Havre de Grace "made sense," one producer told The Aegis.

The show dropped $150 million in Harford County, according to County Executive David Craig. "I tell people the Oval Office is really located in Harford County, about ten minutes from my house," Craig said in a recent podcast of the political show Inside Out. "They said it's Washington, D.C., but I know it's Harford County."
