Immigrants living in America is about as American as baseball. The U.S. is overwhelmingly occupied by people whose ancestors are from somewhere else. On Hello Neighbor Day at PNC Park, people can celebrate those two great American traditions simultaneously. Hello Neighbor, a local nonprofit that pairs refugees with native-born residents, is holding a picnic before the Pirates game. Participants can mingle with immigrants from Africa, Asia and Latin America, all while enjoying peanuts and Cracker Jacks. Discounted tickets are offered, and $5 from the purchase goes to fund Hello Neighbor. Families are encouraged to attend.
