I like to go geocaching with my kids. We own two geocaches in Sweden (one requires a watercraft to access). A few years ago, we happened upon the national Geocoinfest at a local museum. By the looks of most of the attendees, I'm surprised they even leave their home let alone go geocaching or travel.
I have a stash of trackables somewhere in my house from that Geocoinfest. Be on the look out for them...eventually.
