Nearing the 2,000 find mark after ten years of caching on and off, the creative caches have definitely stuck with me more than the rest.

Sometimes it’s a particularly unique container, such as one where a metal tube cache sat at the bottom of a PVC pipe, retrieved by pouring water into the pipe, making the cache float to the top as the water drained slowly from holes in the bottom of the pipe.

Sometimes it’s a particularly creative puzzle, such as one where I had to use GIMP to see what barely noticeable differences the cache owner had made to a picture, revealing the faint outlines of Roman numerals and a Morse code sequence that gave the cache’s final coordinates.

What are some of the most creative caches that you guys have found so far?
