So, geocaching is a massive underground real life “treasure” hunt that’s been going on for a long time. Geocaching came up in a conversation with my dad, an avid bike rider who used to search for geocaches on his rides. Curiosity sparked, I downloaded the Geocaching app yesterday, and my husband and I found this camo-covered medicine bottle at the Burlingame, CA shoreline. We logged our geocache handle and date on the paper scroll, stuffed it back in the bottle and hid it for the next hunters to find.
