The final frontier, some might say (especially those that lived in ancient times, before the thought of space exploration was ever considered possible or desirable), is our Earth's vast oceans. Blue as far as the eye can see in all directions, the ocean provides a domestic option for the adventurous type, one all too familiar to the boys this summer. They've charted a course home, poorly and hastily, and find themselves paddling back to Podford. We can only hope they've stored enough rations for the long and treacherous journey home.
