I've uploaded details of a "virtual" stash in south County Dublin, Ireland, onto my web page at http://www.chris.obyrne.com/GPS/stash2.html
The stash is a word that the hunter must email to me along with their logbook entry, which will be published on my web site. The word in question *is* the treasure - there is no buried stuff nearby.
The WGS84 co-ordinates are :-
Latitude: 53d 15.384' N Longitude: 6d 08.737' W
I'm giving the stash a difficulty factor of 1.0 - though there are dangers for children in the fact that the stash is "on" one of the major roads of Ireland.
