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 orginating 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.
Dr. No is the sixth James Bond book by Ian Fleming. For me the best part is not the adventure on Crab Key, but the beginning when Bond surrenders his Beretta .25 for his iconic Walther PPK. As the following account relates, a letter to Ian Fleming became a major plot element in both "From Russia, With Love" and "Dr. No."
After Diamonds Are Forever was published in 1956, Fleming received a letter from Geoffrey Boothroyd, a Bond enthusiast and gun expert, who criticised the author's choice of firearm for Bond.Boothroyd suggested that Bond should swap his Beretta for a Walther PPK 7.65 mm, an exchange that made it to the novel.
I wish to point out that a man in James Bond's position would never consider using a .25 Beretta. It's really a lady's gun—and not a very nice lady at that! Dare I suggest that Bond should be armed with a .38 or a nine millimetre—let's say a German Walther PPK? That's far more appropriate.[23]
Boothroyd also gave Fleming advice on the Berns-Martin triple draw shoulder holster and a number of the weapons used by SMERSH and other villains. In thanks, Fleming gave the MI6 Armourer the name Major Boothroyd in Dr. No and M introduces him to Bond as "the greatest small-arms expert in the world".

In acknowedgement of the movie, which was actually the first Bond movie made, the geocache is a Decon container
Dr. No does NOT contain a clue to the James Bond Letterbox.
