Dozens of boats on River Seine participated in a rehearsal on Monday with only 39 days to go until the Summer Olympics in Paris. A total of 205 delegations will parade on more than 80 boats on the Seine. The ceremony will drift slowly from east to west, bridge to bridge, snaking six kilometers (3.7 miles) from Pont d’Austerlitz to Pont d’Iéna. (AP Video by Oleg Cetinic)
