A few months ago I sent a colleague a note about the confluence.org web site where individuals send images and a story about their experiences in finding integer intersections of latitude and longitude. During travel from one location to another, Don and Peter realized that they might pass by a "confluence" on their way to the next site. As they explain they were lucky enough to find a logging road which intersected this confluence: no trek into the bug infested woods was necessary. Makes a mundane field trip all that more interesting.
