(ART & WALKING) The map of the 53 sites and 75 artists in this annual alternative to First Thursday includes 17th-century religious icons and a show with a space-travel theme benefiting 826 Seattle. If you would rather not stumble upon greatness but have it thrust upon you, a team of jurors has selected works they're calling "Top Picks" for this year, to be shown at the Phinney Center Gallery. (Greenwood Ave N and Phinney Ave N between N 65th St and N 87th St, www.greenwoodphinneyartwalk.com. Noon–5 pm, free.)
