Zoey Young, 14, of Old Orchard Beach thanks Patrick Dempsey for posing for a photo with her. She and her friends, all "Grey's Anatomy" fans, said they mostly just came to see Dempsey at the Porsches in the Park show at Bug Light Park on Saturday in South Portland. When asked if it was the highlight of her summer, Young said, "More like the high light of my life."
