There are a lot of people from the Pittsburgh area, and all over the place, that have amazing personal stories of meeting Mr. Rogers in person, or how special it was when he personally answered their letters to him when they were kids. Or, if they were sick, would call them personally. Or even visit them or invite them to come to WQED in Pittsburgh to the set of the show. Whenever he went somewhere, he would inevitably be recognized, but he drove his handlers crazy because he would stop and have intimate conversations with random people who recognized him.
And people who met him once or twice found themselves in his correspondence, he would call or send cards or letters. Or if they were going through a rough patch, they would be in his prayers. I heard he regularly got up at around 5 am and had a lengthy prayer session, praying for people all over by name.
One thing about him, is he would bring a camera around with him. When people met him, he sometimes would take pictures with them, as if they were the celebrity, or would call his wife and tell her about the new friend he had met—sometimes passing the phone to them to say hi.
