The house at Hayvenhurst

It is surprisingly unassuming and close to the street-- Michael's childhood home.The gates are plain and share a driveway area with a neighbor on the other side.
How is it that so much magic came from this unassuming place?
Security personnel was polite (unlike some other places) and they were tolerant of the fans who assembled to remember a skinny little kid who grew up at Hayvenhurst...
