For its first several seasons, the show would undertake three or four trips a year to film on location in New York City, combining pickup/overview shots with specific scenes for particular episodes. But the combination of the huge costs and time involved (a brief scene for a Season 5 episode set on the Manhattan riverline took several hours to film) and the show's ratings declining over the years led to ABC first making such trips less common and then, in this final season not having any of them at all. Every scene was filmed on sets in Los Angeles.
