There is an exhibition at the Museum of the City of New York (5th Ave. & 103rd St.) revolving around John Lindsay's two terms in office (1966-1973) as mayor of New York City. It's called America's Mayor: John V. Lindsay and the Reinvention of New York. There is a link here to the museum's web site for more information:
John V. Lindsay and the Reinvention of New York
When I was growing up the story was that Lindsay was despised by just about everyone in Queens because he didn't clear the streets fast enough after a 15-inch snowstorm, so you might expect that borough would stint on any sort of remembrance of the mayor. But it's hard to see how they could do worse than Brooklyn. Behold Lindsay Triangle":
It is at Broadway and Lorimer Street and Throop Avenue and is basically the entrance/exit to the Lorimer Street station on the J and M lines.
Well, at least in the spring, the tree looks kind of nice.
Johnny, we hardly knew you.
