While it is true that you have to bring your own picnic to this affair, free hot dogs and ice cream will be provided. In addition, there will be musical performances, a display of Model A autos, and field games. Picnicers are encouraged to wear vintage clothing of the 1930's. Additional information is available on The Arboretum Foundation website.
While the Arboretum was officially established in 1934 by an agreement between the University of Washington and the City of Seattle, the actual work of designing and planting the 230 acre park was not begun until several years later. This lovely neighborhood amenity for those of us living in Madison Park boasts over 10,000 individual plants representing 4,400 or so species. For those interested in knowing more about the history of the Arboretum there is more background that you could possibly want at the UW's site, including some interesting early pictures and maps.
Saturday's event is co-sponsored by the Arboretum Foundation, the UW, and Seattle's Parks and Recreation department.
