Very narrow cars only beyond this point

The folks living on the Waterville Plateau like their privacy, so to discourage the casual out-of-town curiosity seeker the local highway crews install various tourist traps here and there on their thoroughfares. Obstacles like detours that dead-end in the middle of million-acre wheatfields, the end-of-the-world plunge into a bottomless abyss, and this – The Minimizer- that compresses a regular sized automobile into a very narrow single-seater as it passes through the portal. As the road sign indicates, the less adventurous are encouraged to head for either Spokane or Wenatchee.
