My swim around the world 07/07/07, NEPO 777:

UPDATE: NEPO 777 mission completed. I swam 3 stroke styles a total of 100m at Crescent Beach in Crescent City. The 100 m length was not linear, but rather curvilinear, in an arc around the oceanic hydrosphere of Planet Earth. This was a trial event in preparation for a circumpolar route around the entire planet, following the coasts when possible, with a dive partner, abundant funding and proper equipment.

NEPO 777: Neptune, Mediterranean legendary hero of the sea. Poseiden, Mediterranean legendary hero of the sea. Capt. Nemo (Principal character in Jules Verne's 20,000 leagues under the sea). 07/07/07: Anniversary of my father's birthday.
