On the first Saturday of May for a century, hundreds of recreational boats have paraded from Portage Bay through the Montlake Cut for Seattle Yacht Club's Opening Day to celebrate the official opening of Seattle's boating season. After the Windermere Cup—in which impressively strong-limbed people from the University of Washington compete in a series of races—watch from the shore as adorned vessels boast live bands and giant floats. It's also a tradition for people on board to throw water balloons at shore-dwellers, so practice your reflexes.
