It started in a Hog’s Breath car park, in the middle of a Friday afternoon. My girlfriend directed me towards a tree, the compass on her phone spinning around and pointing towards it as we explored the surrounding area. It was a clear day, and the GPSguided compass claimed accuracy within one meter. I was searching for my first geocache, becoming part of a global phenomenon I had heard mentioned in hushed conversation for years. We found the cache fast – a small plastic container, containing a log book and a pencil for us to ‘check in’ with. We wrote the date and our usernames, logged the find on the app with a few comments, and set off for the next one.
