"As a whole, geocachers are less likely to be Darwin award winners."
Geocachers run the gamut for intelligence, just like all other hobbies and sports. There are 'geocachers' who try to find a cache in a wilderness area while driving a low-clearance vehicle like a Corvette. Owning a GPS and registering with geocaching.com is all you have to do. Brains and sense help, but are not required.
