York County, Maine Residents: If you can say, “I’ve Driven By Several Times But I’ve Never Been Down the Driveway,” we would love to invite you as our guest on June 17th and 18th. Bring proof of residency and we’ll give you free admission! We’re the world’s first and largest transit museum of its kind, and we’re right in your backyard. It’s time to cross us off your bucket list and take a trip to one of the most fun spots in southern Maine! Take a ride on our heritage railroad and enjoy exhibits and display around campus. Bring a picnic lunch! Also, if your dog is friendly, we’re dog friendly.
