MARION — The Sippican Lands Trust will be celebrating its final 50th anniversary walk and its traditional post-Thanksgiving dog and human “waddle” Sunday, Dec. 1 at 9:30 a.m.

The walk will leave from Hoff parking lot, or if the parking is full across Route 6 on Abels Way.

The walk will be about 4 miles, and there is no hunting in Massachusetts on Sundays.
