The last two remaining installments have both been identified, at last! UI 35 is Elliot's house from ET: The Extra-terrestrial (it's the one with the longer driveway), while UI 37 is the Timberline Lodge on the slopes of Mt Hood in Oregon. As usual, one thousand Quatloos to the winner, although that winner is proving to be the same person each time out, so either I have to make this harder or reduce the prize. Heh!
Anyway, time for the new location.
Where are we? Rot-13 your guesses, folks!
