Mar 14, 2007 — This Friday and Saturday, Mountain Lake PBS will broadcast their new documentary called "A Castle In Every Heart." It's the story of Arto Monaco, the Adirondack inventor and toymaker who created some of America's earliest theme parks. Monaco's creations in the North Country included the Land of Make Believe in Upper Jay, which he built in his own back yard. Coming up in the second half hour, we'll hear Brian Mann's interview with Arto, recorded just a year before his death in 2002. But first, Brian talks with filmmaker Derek Muirden about his friendship with Arto Monaco and about the new documentary, which will air nationwide starting this year.
