A GPS receiver can identify your position within a metre or so. So what do we do with this? Invent a new game called Geocaching. Geocaching involves finding a small container concealed in the middle of nowhere and recording the fact that you have found it. Fun? It is rather, particularly when trying to find the container when one arrives (roughly) at the right place. There are millions of Geocaches concealed round the world. Geocaching.com will identify ones near a postcode or lat/log reference. There are 50 caches (yes, 50) within 2 miles of Little Hampden!
Here’s a map of the caches round Great Hampden
