Tom's Brother: Many thanks to Palika38 and Trevorthedog for reporting a "Didn't Find". I've checked the cache site today and, sure enough, it has gone.
The area is much more open than when the cache was first placed, so I guess that muggles have taken it.
Thanks to everyone who found the cache over the years and for all the kind words many have written. There are still some cachers left who say a little more in their logs than merely " found it" or "TFTC" or something equally terse :-).
