Grandest Kids Alyssa and Gabriella Harris, ages 5 and 2, are from Machenbach, Germany. They made a trip back to Pennsylvania in August to visit their Oma and Opa Gary and Sylvia Serfass of Lehighton. The girls got to visit the sights of Philadelphia and New Jersey. They also went to Dorney Park, Becky's Drive In and the Lehigh Valley Zoo and did lots of shopping while they were here. They spent a lot of time swimming in their Oma and Opa's pool and playing with their great-grandmother, Helen Keiser and great-grandfather, Kenneth Serfass. Their parents are Sarah (Serfass) and Austin Harris. They have lived in Germany for the last six years where Austin is currently serving his country in the United States Air Force. Sarah and Austin are both continuing their education with the University of Maryland while stationed overseas. Austin grew up in Decatur, GA, and his parents are Claire and David Harris. Alyssa and Gabriella, along with their mother, returned to Germany on Aug. 11 to start school. While Alyssa starts kindergarten on Ramstein Air Base, Gabriella attends the Children's Learning Academy.
