Remember that Canadian fellow who paddled the whole way around Taiwan a few years ago? We followed his adventure on a thread here. If I recall correctly, he got at least some recognition from officialdom and the media for it (though I’m sure many officials were anxious lest locals should be inspired to follow his example).
