Across the Hudson River, Thomas's initial breakdown in the opening scene was filmed in the Newburgh library, looking out across the river, and Dominick and Dessa are shown entering the terminal at Stewart International Airport near that city in flashback, where she boards a flight for Europe. In addition to the Ellenville car dealership used for the scenes with Leo, some other locations in Ulster County were used, including Awosting Falls in Minnewaska State Park Preserve on the Shawangunk Ridge west of New Paltz. The Springtown Truss Bridge on the Wallkill Valley Rail Trail across the Wallkill River north of that village, also known for its use in the opening scenes of the 2018 horror film A Quiet Place and its unreleased 2020 sequel, was used for the flashback scene where Dominick and Thomas's grandfather throws a bag with a live monkey into the river. A section of U.S. Route 209 outside Kingston also was used for a confrontation between Dominick and Thomas in the first episode; the road was closed for two days in both directions for filming.
