I love the TV show Doctor Who. This series is all about The Doctor's companions on his travels through time. There are six caches in this series: Prof. River Song, Rose Tyler, Captain Jack Harkness, Ryan Sinclair, and Brigadier General Lethbridge-Stewart. There is a bonus cache once you find them all, so don't forget to write down the clue found at the top of the log in the cache!
Pond meets The Doctor as a young, strongheaded girl and remains strongheaded throughout their lives together.
