Looking for a low-cost adventure? How does free sound? 

The day after Thanksgiving may traditionally be known as 'Black Friday,' but The Trustees are encouraging families to skip the shopping malls and make it 'Green Friday,' instead. On Friday, Nov. 29 Trustees are offering free admission to all of their outdoor properties. 

Properties from the Berkshires to the Cape will host family fun activities, like story walks, guided hikes and tours, artist markets and more. Get all the details at here.
