very impressive boss- though no mention of the sextant,which i assume you,like most europeans, used as their main guide when you traveled the oceans. Hope the ravens got fed.

Its interesting what you can pick up when exposed to a certain environment. When working in construction etc art a lake for a couple of years i could tell the time within 10 minutes just by looking at the sun (children- dont do this -only professionals should do this) so I'm sure the natives had certain special abilities in their environment as implied in the video.
