Every time my nieces and I go "treasure hunting" (both letterboxing and geocaching -- Eva likes letterboxing, Delilah likes caching), they always want to hide one for people to find. Today I happened to have some ready-to-go bison tubes on me, so that is what you're looking for: a blue bison tube. They chose the location and the name and are super excited for you to go find their very first hide.
