For those interested, I did a search for the track location where the Moscow 500 Unlimited takes place.

The track resides within what is called the Dmitrovsky Car Range in Dmitrov, Moscow.

In the image below, the track used for the mile long races is outlined in yellow.
This section of the track, from turn-around to turn-around, is just about 3 miles long.

The races begin at the north staging area.

The balance of the track system can be seen to the right in the photo.

Boy, do I wish we had something like this available near me!

Anyway, I found it interesting and felt like posting it up.
Not sure if there is a better place to post this, but I felt it would be appropriate here.
