Immediately afterwards, Grant decided to run into the water to "take a swim" (a.k.a - hide the big, beach boner he popped in his tight, little Euro-swimtrunks he got from STARING at Sarah's titties.)
All the people dressed up and participating in the parade start on the boardwalk, walk down the beach through three gated ribbons, each representing a season, and then march the entire parade right in the water, officially bringing in the summer.
