You might contact Jeff at the KOH website and see if he can send it to you. They issued one to the drivers before the race.
I have GPS of all the Hammer Trails in a kml file. If you want a copy, pm me with your email and I'll send it to you.
Okay, I've put the kml file on 4shared files so anybody that wants to can download a copy of it. It will open right up in GoogleEarth if you have that installed on your computer.
