00:00 Geocaching is the topic of discussion in this episode of "Stuff You Should Know" podcast.

03:18 Geocaching began as a result of President Reagan making GPS commercially available to the public in order to prevent incidents like the Korean Airlines Flight 007 being shot down by the Soviets.

07:12 Geocaching is a treasure hunt where people use GPS coordinates to find hidden caches and leave their own trinkets.

10:37 Geocaching websites provide coordinates and lists of caches, and it's recommended to start with a cache close to you; some caches are hidden with sadistic glee to make it more challenging, and it's important to not put illegal drugs or alcohol in caches, but instead leave inexpensive items like CDs, DVDs, or handmade trinkets and sign the logbook.

13:53 Geocaching can involve taking pictures with disposable cameras, trying to get trinkets across the country, and using geocoins to track their journey, but it's important to be respectful of the environment and not cause damage or leave caches in inappropriate places.

17:21 Geocaching can involve different variations such as multi-caches, letterbox hybrids, and virtual caches, each with their own unique challenges and experiences.

20:51 Geocaching has its own lingo and community, and it is a family-friendly and open hobby that can be enjoyed by anyone.

24:29 This section of the podcast includes listener mail and a discussion about Wisconsin city names.
