I'd like to add Dinghies Whidbey Island to the race calendar up here; it fixes to be the premier event for sailing in the PNW. Last year was the first year of dinghy racing, and this year we'd like to have 7-10 boats on the line.
Whidbey Island is a ferryboat ride away from Seattle, and is well- known as "summer camp for grownups", with bands, volleyball tournaments, alcoholic beverages, and comisserating with other sailors.
The racing will be July 17th-22nd, and should be very well run by the race committee. The website for the racing is here.
