I have been walking my dog, often with family and friends, around Lexington’s Old Reservoir for, well – my third Labrador is now in her middle age, and her immediate predecessor had a very long life – it has been years. Circumambulating the pond at least once and sometimes two or three times a day across the seasons has given me the opportunity to experience the Reservoir’s changing light and mood with the depth and intimacy of long acquaintance. It is a pensive place for me, especially in the quiet beauty of off-season, filled with sometimes quirky reminders of summer – a forgotten snack jar, a misplaced picnic table – and unexpected playful moments. The Old Reservoir has given me quite a gift: a deepened appreciation for the importance of the small, day-to-day places where people and nature (and even dogs) connect. For the transitions that mark the passage of time.
