“Geocaching” is an activity where people seek out hidden treasures with the help of GPS. Strangers will hide a box or capsule and note its coordinates. Then, other people will attempt to find the hidden cache by locating it with GPS. It’s basically a modern day treasure hunt. Some people get really into it, which is so cool.
A Reddit user decided to participate in a geocaching hunt (in epic fashion) by making this cool hiding place for his capsule. Finding this would take some serious effort, but it’d be worth it.
