Seattle Cherry Blossom & Japanese Cultural Festival is this coming weekend, April 20-22, 2007. I've never gone, however "The campaign continues at this year's festival by bringing cherry tree experts from Japan to Seattle to teach Washingtonians about the proper care and maintenance of cherry trees. The cherry tree experts will give instruction during the festival and the week that follows." http://www.seattlecenter.com/events/festivals/festal/detail.asp?EV_EventNum=4
