On the way home from the Television gig, walking through Central Park (which is gorgeous) we stumbled across the ' Imagine' shrine.
Several months ago I read some 'secrets of new york' article and it mentioned a story about a homeless man who is donated flowers each day from a florist and then places them in a different arrangement like this (this is just beside Strawberry Fields):
It was really nice to come across this without expecting it. And to know what it was straight away.
