So much has been written about Bumbershoot 2008 — Seattle’s #1 Music & Arts Festival, August 30-Sept. 1 — that to write much more here would just be dull overkill. The one thing I can do, though, is point you to the The Stranger’s excellent Bumbershoot guide, which consists in part of a utility that allows you to design and print a custom itinerary of the acts you would like to see at next weekend’s festival. And there’s a lot to see.
