Here is some great footage from the 1904 Vanderbilt Cup Race. Try and imagine a Nascar race if they allowed the crowds beyond the fence.

Here is another video from the 1906 Vanderbilt Cup Race.

This last one takes a very interesting look at various parts of the track when compared to then and now. I wonder how many people have walked on some of the closed sections without having a clue as to what used to take place there let alone those who took part in it.
