The Roxbury Land Trust will play host to a Sunset Celebration at its Gavel family farm preserve Sept. 19 from 5 to 7 p.m.

The free event on Upper County Road, near the intersection of Route 317, is the culmination of a summer-long series of events honoring the land trust's 40th anniversary.

In case of rain, the event will be held at Hurlburt Community Park on West Apple Lane.

Interested people are encouraged to bring a picnic and blankets and/or lawn chairs.

Dessert will be provided by the land trust and instrumental music will be offered by Chris Merwin and Paul Mueller of Mecca Bodega.
