Summer fairs and festivals continue: This week Fremont Street celebrates and the Washington Park Summer Festival kicks off 10 days of amazing shows. Trekkies will transport in droves to the annual Trek in the Park festival. You can catch a new concert series out at Evergreen Aviation. And another inaugural event takes root this weekend: Dirt to Dinner at OMSI. It showcases the life cycle of your food and helps your family understand how your eating habits affect the environment in a fun, engaging way. We dig that.
