With Brain & Pinky, Eikenhofjes and Xizat I travelled 11 days through the USA to find some very old caches. On our 6th day we went for GC16, the Original Stash Tribute Plaque, GC12 and GC17.
Due to the large number of favorite points, we stopped at Slider. We found a tube for which we fortunately did not need water (or beer). We recognized the system and quickly retrieved the cache.
Thanks and cheers!
