It’s National Ice Cream Day on Sunday, and Pennsylvania’s Ice Cream Trail is celebrating. The Trail is a partnership between the state’s Department of Agriculture, the Center for Dairy Excellence, and the Department of Community and Economic Development and Tourism. National Ice Cream Day has been a thing for over 40 years now, and many ice cream shops will be offering more than just free samples this year. Pennsylvania is highlighting its Ice Cream Trail this year. You can find out more about the trail at the state’s tourism website, VisitPA.com.
