Thanks everyone - glad you enjoyed them. It was the perfect weekend!
Fires are permitted in the Sandwich Wilderness area, and we're expected, of course, to leave no trace. I think that the allowance of fires in this area is fairly recent.
In one site we used an established fire pit, and in the other we had a small fire with only downed wood. We made sure to scatter the ashes and replace ground cover before we left in the morning. We left it as we found it so that YOU can enjoy it!
