You know who else have a Maine vacation home? The Bush family.
Lots of the ultra-rich have property on the Maine Coast. Acadia National Park was donated by the Rockefellers. Many recognizable American brand name families own property on MDI as well as celebreties.
(of course only for the Summer, so as to avoid the long Winter and the Maine income tax)
My daughter’s is in Cape Cod.
Robert's is about 100 miles northeast of the Bush compound at Kennebunkport.
