My wife is awful at map-reading so she gave me a GPS for Christmas 2000 (cheaper than a divorce)! It was a gamin eMap which I only used in the car to start with. I read about geocaching in early 2001 and liked the idea but the very few caches within 30 miles of me were in areas closed to the public due to Foot and Mouth disease.
I finally remembered about geocaching in the Summer and we went to find our first cache which was https://coord.info/GCBE3 (The Queens Oak, which is still active). That was on 1st September 2001, roughly a 30 mile drive from home. We weren't sure what to expect but loved the experience so much that we went out to find our second cache on the next day (which was still unfound after 7 days since it was placed).
Caches were a long way apart at that time with about 20 caches within a 30 mile radius of home in Southern England. In the early days we used to print every new cache page in England just in case we went anywhere near it, which lasted until we filled a lever-arch file and the number of new caches exploded
