Trawling the downtown area for architecture sounds like a perfect afternoon—mix in a competitive aspect and it’s even perfecter. This scavenger hunt aims to draw your attention to local architectural marvels that you might otherwise pass by. Teams of five assemble for the hunt of a lifetime—and if you can’t make a team or prefer to meet new like-minded people, you will be assigned a team. Winners get trophies, and you all meet at Hot Italian at 4 p.m. for the closing ceremonies. AIA Central Valley, 1400 S Street, Suite 100, ea18designhunt.brownpapertickets.com.
