While I really love IOW and it's an awesome (and my main) source of Indiana dirt track information, I'm also a member of a Facebook group that includes fans, drivers, car owners and some racing photographers. It's become a really awesome way to connect with fans, stay on top of big events and share pictures and thoughts about racing.
If anyone would like to join, I've posted the link below. Just keep in mind this goes beyond open wheel racing and includes stock car fans as well. So there's a little bit of everything.
