I have a thought on starting a different type of "Cache" What if you gave a location to a local historical sight and when the finder gets to the site he/she records the information and then has to go to a web site to find out the story. One thought I had was to provide a location to a headstone in a cementary. The finder would record the name on the headstone along with other information, then go to a web site (Groundspeak??) to read about a local legend concerning that person.
