Tracks4Africa

Loading stuff onto Google Earth, I kept coming across something called Tracks4Africa. I finally had a look, and it's a group of (mostly) South African eco-tourists who are using Garmin GPS to create accurate maps of Africa for tourists. I'm not sure if my tracks will be any good, but it's another thing to remember if we do anything like this again - there are millions of miles of poorly-mapped road but growing legions of tourists travelling them with GPS devices.
Probably worth sharing with the rest of the group, too.
