The Ferret Named Felicia Delivers

The ferret named Felicia was a great success. After completing a few trial runs, spurred on by the promise of snacks, she went on her merry way into the four mile long tunnel. A recon mission failed to turn up any blockages, so it was back to the drawing board or more specifically the mathematicians and after a couple more paragraphs. They wanted to see what happened. We've all been there.
