The biggest weekend of the year is here for both art lovers and Seattle old-timers. We’ve got a link to a guy who explains just why the hydroplane races are still important. We’ve also got a guy who quit running for office but made it to the top-two general election anyway; the need for affordable housing in the ‘burbs; the threat of technological thought-reading; a nascent “co-op” nightclub; and dozens of event listings, art-related and otherwise.
