This weekend, from Friday, November 27 thru Sunday, November 29, the Massachusetts Audubon Society is hosting a Hike-a-thon. Anyone can join Hike-a-thon from anywhere! And all types of hikes are encouraged—from a stroll around the neighborhood to trying out a universally-accessible All Persons Trail to taking on a challenging summit hike. They are encouraging people to register ahead of time. There's no charge to participate, but donations are welcome to support MassAudubon’s mission.
