Seattle Parks has released an online guide (but you can print it) for fun in the parks around the city this summer.
While not many of the events included are West Seattle specific (though they do mention the Alki Community Picnic on August 31) , it's a great guide for planning to attend a wide range of things from outdoor movies at Hing Hay Park in the International District to free events for the arts, culture and as they say, "just plain fun," all around Seattle. Get out there and enjoy our city.

The 16 page guide can be downloaded and printed at this link.
