>>199371Travel Bugs are little dog tags with a unique code printed on them. You can type that code in on the geocaching website, and it will let you post that you took the tag. People release them with a goal - the idea is that other cachers find it, realize they are going the direction it wants to go, and takes it with them, then drops it in a cache closer to it's goal.
Generally, they end up moving 3-4 caches before they get lost and never seen again because some shithead keeps them, generally a newbie. I released four of them three years ago. The best one made it 900 miles and six caches before going missing. The others less than.
>>195715Depends on the cache. The vast majority lead directly to it, no deviation. That's the point. Puzzle caches and multi-caches will bring you to something else, where you can find the coordinates to the cache. It's within one mile.
>>190470You don't hunt for them with the intention to keep things. They are generally useless trinkets that are just there for fun. The point is the cache, not what's in it. OP's picture shows what is generally found in a cache.
