The Westborough Community Land Trust is hosting a walk through some of the town's conservation land at 1:30 p.m. next Sunday  to savor the beauty and wonder of autumn in New England. The 90-minute walk will follow trails in the Headwaters Conservation area, with the route starting at Mill Pond School. The group will stop by the Assabet River and proceed around Osprey Point for a view of Mill Pond, and then explore the butterfly garden before returning to the school on a different trail. For more details, e-mail events@westboroughlandtrust.org.
