Other Research Links with Excellent Content

I have received so many wonderful comments about FirstSuperSpeedway.com, and I'm very grateful for so much positive feedback. I want to take the time to recognize a couple of sites that I have tremendous respect for as I use them frequently in my research. One is Champ Car Statistics and the other is Darren Galpin's pre-World War I content, which is part of a larger site. I call these to the attention of anyone researching this era of motor sport. Both strike a nice balance with the content on FirstSuperSpeedway.com.
