The movie supposedly takes places at Lake Tahoe. They even used a lot of stock footage to show it. However, once cast arrived at the lake, they are surrounded by deciduous trees, some even have yellowish leaves, and there is a lot of yellow leaves on the ground. The real Lake Tahoe is surrounded only by coniferous trees. The movie was actually shot at some lake in Kentucky. Furthermore, around the half of movie, they stopped to use Lake Tahoe stock footage and switched to the above-mentioned real lake somewhere in Kentucky.
