At the 46:52 mark, James gets out road map of Lindenville, WA which shown to be a small town with a lot of moisture. The map is actually showing Yakima, WA which is a small city in a very dry climate. The movie makers also edited the map to remove other city names but left all the roads. But the map still has some distinct names such as Tieton River, Bumping Lake, Chinook Pass, Crystal Mountain Resort, and Mt. Aix
The name of the town Lindenville is derived from the name Lynden, Washington, which is a town just south of the Vancouver, British Columbia where the movie was filmed.
