We did the 11 icons in 11 hours challenge at the Geolympix and I remarked to RubyShoos that it was a pity there wasn't an actual cache to collect at the end to mark the challenge. So thanks for doing this.
Qualifying caches on my webpage.
We found the cache in the obvious place but scratched our heads a bit at the hint ("take a rest"). Then we realised we were looking at the hint from a different one.
