Originating in America in 2000, Geocaching has become a worldwide pastime; there was even one on the International Space Station until 2017.
The Geocaching concept is relatively simple. A Geocacher places a waterproof box with a log book, a pen and trade items. These are usually small, worthless items. The box position is then placed on a listing with its coordinates.
Other Geocachers then check the list for boxes and using handheld GPS, can find its position. There are full instructions on the lid.
I found mine by accident whilst out moochin'. Unfortunately the rain had got in ruining everything. Nothing's perfect but fun to find. Being camouflaged I thought it was a pest trap.
