Blue moons don’t come around often; come celebrate with us by joining our Passport Discovery Hunt! Travel NW Portland to solve the four clues and snap a photo of yourself with the artwork in question. Once you get your pic, show it to a staff member at the Blue Moon and you'll get a stamp and a special Blue Moon pint glass and be entered in a drawing for an overnight stay! No purchase necessary, you just have to snag those pictures and get the Discovery Stamp! Valid on May 18^th only. Limit one per person. Ages 21 & over. You must be in each photo.
