    "I lived here for 38 wonderful years, made many great friends through active community in sports, Scouts, PTA and job. Neighbors respect privacy but are always there to help in time of need. Each season has it's own beauty but my favorite is Spring, after a snowy winter, to see the abundant bulbs in bloom."
