Sail Sand Point
The summer may be ending, but it's not too late to step the mast, rig the sail, and head out on the open water of Lake Washington. This Groupon gets you an adult unlimited sailing pass for the rest of the year to Sail Sand Point, located along the western shore of Lake Washington just five miles north of the University of Washington. A membership gets you and up to three friends out on the water with access to Sail Sand's range of boats. The adult pass is normally $175 for the whole summer, whether you buy it in May or September (though they do offer an early bird special of $150 if you purchase before April 1). With this Groupon, just $50 will get you in on the action for the rest of the 2009 sailing season. Note: Sail Sand Point closes on October 15—that's two months of sailing and access to Sail Sand Point boats.
