(GRAND OPENING) The hotly anticipated grand opening of 826 Seattle is upon us, and today's party for the public is a fine time to see what all the fuss is about. The writing center for humans aged 6–18 is fronted by a space-travel supply store you have to behold to believe. Plus, today's extravaganza includes live music, readings by Ryan Boudinot and the worship-worthy George Saunders, and an I'm-just-here-checking-things-out appearance by 826 founder Dave Eggers. (Greenwood Space Travel Supply Co., 8414 Greenwood Ave N. Noon–6 pm, all ages, free.) CHRISTOPHER FRIZZELLE
