Thinking of you Aunt Dianne and my cousins. Many fond memories of gatherings with our families, and Uncle John's pipe glowing while we ran around in PJs during snowy thanksgivings in Rochester. Some great vacations together and the best one was when you all came to Northboro in your camper. Uncle John was a great man and will be missed.
