The 1984 (?) Anti-Nuclear protest in New York City brought over a million people into the streets and Central Park.

The 1982 (?) Simon and Garfunkel concert in Central Park brought over a million people also.

Are there pictures of these events that could be used for comparison with 8/29/04 protests?

During the 1984 march, how many blocks did the march stretch?

(I hope have my years right - I might be +/- a couple years.)
