The Ian Fleming's James Bond series of geocaches honors the amazing original books (not the movies). It is placed along a section of General Crook trail originating from the Rim Trailhead. Most are small geocaches, but caches named after my favorite books have a clue in them for James Bond Letterbox. Designed for biking, this powertrail is spaced .25-.5 miles between geocaches (because 0.1 mile spacing on a bike is very tedious).
Moonraker is second book in the series. Unlike the Roger Moore movie version involving space shuttles, eugenetic conspiracies, and in-space laser fights, the original novel starts with Bond outplaying Hugo Drax at cards, which uncovers the latter's cheating. Almost coincidentally, Bond later is sent to oversee the "Moonraker," England's first ICBM prototype. Bond escapes multiple assasination attempts and uncovers a consipiracy to drop a nuclear warhead on London. Hugo Drax has a one in a million ending. Moonraker further develops the character of James Bond, describing his personal day to day life, and he doesn't get the girl in the end. It is the only Bond story based entirely in England.
Moonraker does NOT contain a clue to the James Bond Letterbox.
