In a transition scene before the Threshold team uproots the preacher's garden, we see images of what are supposed to be the area in Indiana where they're investigating. However, one of those scenes is actually of Harvard square in Boston, where we see a Boston bus and a well-known house on the grounds of Harvard.
At approximately 21:26, the intersection shown of the Indiana town is actually the intersection of NY-96 and US-20/NY-5 looking west in Waterloo, NY. The GPS coordinates of the view are 42.904593N 76.86239W.
