San Francisco celebrates this holiday that is actually a global holiday- the Summer Sailstice. Bringing everyone together who loves water and wind in the hair on a beautiful sailboat, this is the event to celebrate that summer sunshine and proximity to a beautiful bay. Gathering everyone onto Treasure Island, the fellow sailors will enjoy live music, big boat races, boatbuilding contests and looking for buried treasures for the kids. Enjoy a weekend of sail and the sand for the Summer Sailstice.
