Years ago, I worked the ferry run from Hyannis to Nantucket. There were rumors that Mr Rogers owned some waterfront property on the island. There were further rumors that he was less than an ideal neighbor and wanted to build up the property, such that some folks would have lost their view of the Sound. I've never spent time to confirm this, and kind of think it was just people with too much time on their hands making things up, but the folks that I heard it from had all sorts of bees in their bonnets about it. Don't know if they still let their children tune in.
