Grades 6-12. Join us for the ultimate Oreo taste-off. We will have multiple flavors of Oreo cookies on hand to taste and rate, from best to worst flavors. We’ll provide the cookies (and milk)! Space is limited. Registration is required. Free. Please email odurant@minlib.net to register, or call (978) 318-3379. You may also register on the Library’s calendar of events at https://concordlibrary.org/news-events/events-calendar/.
