The "people of interest" do deserve their privacy but a few years ago I discovered that there is an attorney in the Wolfeboro area that works with these people and through trusts, corporations etc. makes it very difficult to really know who owns what. The atty's name appears on a lot of deeds but not that of the actual owner.
Some do hide but I know of one very well known New Englander who does not hide their identity when here. They were recently seen in southern NH buying one of their favorite things to collect and had it transported it back to LA.
The event was actually video taped and could show up somewhere on TV but I do not know that for a fact it will.
