Ah Dave? They wrote NOTHING! But their response to my positive note was to say a little something about their find, something more folks should do if they have the imagination. I still say it's not good etiquette to not at least thanks the CO for placing the cache...even the "lame" caches. By the way, the cache was my Schooners R Us cache on the water at Camden Harbor. Most folks respond favorably just due to the scenic beauty of the area.
Sometimes the road less traveled is less traveled for a reason.
