I discovered this in the weirdest places today. I was in a rock pit (long story) working with a guy who I at the time did no know was "Inspector Gadget, a person who has found many of my geocaches over the years. He showed me an interesting device he had and I asked him if he was into geocaching........then we had a long chat about it and he showed me his tattoo of his trackable. You just never know who you are going to meet, that is forsure.
You are quite the geocaching pioneer! It was great to meet you. See you soon.
