Space A, is a common military annotation for available passenger space on a flight to a far away destination. We could also say something along the lines of: "Space, the final frontier. This is the voyage of the geocacher, in a multi-location mission to search out and find new hides for a geocache." Sometimes finding available space to place a geocache is difficult, many times it is easy. It all depends. As more geocaches, with the mission of providing long-term enjoyment, are placed. Finding a spot for a new geocache can be challenging. This geocache was placed in recognition of that challenge. Just enough space to fit just one more in this zone. I will place more, as Space is found, and hope you will as well.
