In my dreams, NYC transforms overnight. Manhattan is no longer the island of the super-rich. The ubiquitous advertising is gone. Everything is art. In fact it looks a lot like The Heidelberg Project outside of Detroit. This alone is a reason for a trip to Michigan.
The Heidelberg Project was started in response to the homes left abandoned after the '67 Detroit Riots. Tyree Guyton (and his wife and father) got the kids together and went-a-decorating. It's truly inspiring.
