In which city was the very first Wherigo, published?
The answer : London
The Where I Went, Hugo geocache (GC18FP7) is the very first Wherigo, published in London in January 2008, only weeks after that cache type opened.
Wherigo relies on a cartridge to download and run on your device: at the time, a Garmin Colorado or a GPS-equipped Pocket PC. The route is deliberately simple — under an hour — because it was rodz's first attempt at the format. A physical container waits at the end, holding the final code that completes the cartridge.
