What if Portland is short for or a nickname for "Portal" Land...

If one does not examine the scene too hard, that looked more or less like the Pacific Northwest (amazingly).

32 miles outside of Portland (assuming this was Portland, Oregon) -- I'm curious: Which direction from the city were Ben's parents hiking? I can drive there in little time.

((Allow me to clarify: I'm joking. I know it wasn't filmed anywhere near Portland.))
