The hobby described in section A

The hobby described in section A involves going outside with a special device like GPS or a smartphone app to find hidden containers. These containers, placed by other people, aren't filled with gold or jewels, but instead hold a logbook or trinkets. The challenge is to find the containers by carefully exploring parks, forests, or cities, which can feel like a real-life adventure. It's a social activity because there are communities worldwide that share tips, create new challenges, and celebrate successful finds. The excitement comes from the search itself and the feeling of accomplishment when you locate the hidden item.
