Keith, A great idea. And it should not be impossible. In the States both the Adirondack Park in NY and The National Seashore in MA show the way. Both enclosed much private land, homes and activity. Always contentious, and still is here in the Seashore where I live and work to preserve the good stuff, but both efforts ultimately successful. So congratulations from your US guest, a one time logger, 26 year Salmon fisher, and admirerer of your visionary imagination and writing skill.
