Karen rowed for what the venerable American shell builder George Pocock called `the symphony of motion.' As dawn breaks over the river, the shell is lifted from its rack out into the morning. On another rack the oars hang ready to be greased and slipped into the locks. Then, awakened to the river and the feel of the oars, the oarsmen blend in fulfillment of the shell. The symphony is not of competition. It is the synchronous motion over water, the harmonic flexing of wood and muscle, where each piece of equipment and every oarsman is both essential to, and the limit of motion itself.
