A friend of mine found one of my caches today that had been muggled. It was empty and had a log in it with something about 'geo-doggy doo',
beside it he found a bag with a pen and notebook inside and a whiteboard which was not actually part of the cache.
Seems to me someone muggled the cache, and threw it over the fence just to have it accidentally land beside some kids attempt at a geocache.
weird I tell you!
