 Since production had moved from Vancouver to Los Angeles after the conclusion of the fifth season, a local California location was needed to stand in for Oregon.Consequently, when the cast and crew of the series finished filming at the Fox lot, they relocated to the Big Bear resort, located near Big Bear Lake, California, which was very evocative of Vancouver, thereby providing an "ideal backdrop" for the episode.The episode featured several elaborate effects, created through both digital and physical means.
