This is a sketch from my series "Swim Postcards" that I do to capture memories, feelings and fleeting glimpses from swimming in the San Francisco Bay.br/br/We were at the flag buoy, and turning back to the club, when my swim buddy said "I think my foot just touched seaweed". The sensation repeated itself - but more insistently and with more resistance. The last time it happened, my swim friend could feel the animal's whiskers on his legs. Turns out it was a playful seal, who we immediately dubbed "Whiskers".
