This run supports OSPR (Old Saybrook Parks & Recreation) and the multiple ways in which they aid in early childhood development and learning, as well as call attention to The Preserve. The wetlands and swamps of The Preserve, a 963 acre forest right in our backyard, provide drinking water supply to two towns, and are home to many species of conservation concern.
