Cape Flattery, Washington: The very NW corner of the continental United States! It was dark and rainy the whole trip there and back (and a very windy hilly road which challenged my Forester, which ripped right through that!). It was not the most impressive thing with the clouds obscuring everything, but the final picture I saw in my rearview mirror on my way out which resulted in an immediately reversal and grabbing for my tripod and camera!
