How cool was this local geo-caching event...start in the cemetery (muah ah ah) and look for clues like "how old was grandma?"
I love the trickier navigations that people leave and that you get to bring home a treasure from the loot. Middle man came home with a blue caribeaner (he gave me strict instructions not to use it mountain climbing- "it's not a real caribeaner", he said) and left in it's place some sort of sea creature (not real, of course.)
And seriously, could grandma really have been that old???
