...and the winner is.... BECKY LAPOINTE!!! CONGRATULATIONS!!! This door is on a building at Custer Airport. Drive down the airport road, look at the first building on your left. WHY it says "Relaxation Clinic" on the door... who knows that one?
Zoom in to the door to see a major clue to where this door is.
Becky - if you're at Redeemer this Sunday morning I have a very small gift for you. :)
