Wow, Bruce, that place is maybe 10 miles, as the crow flies, from where I grew up in Enfield, CT! We used to fish and go tubing in the Scantic river as kids, it's not much more than a scenic meandering river in most places but it does have a few short rapids here and there.
Lots of history in that area of New England, just about every town has an Historical Society that mandates what you can and can not do with historical places like that house. You can't move a rock from a stone wall without their permission.
