This is the 160th anniversary of the celebration and so in addition to the art show there will be a parade, street faire, beer garden, living history exhibit, artisan farmer's market, and a concert in the park. In case you aren't from around here, Aurora is the site of a 19th century commune, the founders of which traveled to the area via wagon train on the Oregon Trail. It's a small town full of beautiful old homes, artisan shops and antique shops.
