The exchange between the “Andrews” about longitude suddenly reminded me of a book I read in the years BC (Before Caching). It has the rather long title of Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time, and it’s written by Dava Sobel. The title pretty much sums it up. It might not sound like interesting reading, but I couldn’t put it down… and that’s before I even knew what a GPSr is. Could be a good one for you to take on your summer vacation.
