Most geocaches expect you to take an item (usually a knickknack like a keyring), leave an item of your own and leave an entry in the logbook.
This cache is different. It is an I Ching cache, whose original contents are 64 slips of paper, each bearing one of the hexagrams of the I Ching (the Chinese Book of Changes) and their brief interpretations.
How to use the cache
Please don't leave normal geocache items in this cache: it should basically contain nothing but the 64 answer slips and the logbook. However, small travel bugs are welcome, as long as they don't squash the paper.
The cache is located on farmland near the Staffordshire village of Hints, just a few metres from a public right of way. This is a really lovely area for walking and cycling. I'd never been there before the day I placed the cache, but when I saw it on the map I knew I had to put a cache there, just because of the name and the way it looked on the map. I suggest you get OS Explorer map 232 and explore the area properly: make a day of it.
