Well friends, wonder no more.
I have devoted countless hours of my time to painstakingly placing points on a map [read: I got bored at work] so that you may find, with ease, your nearest track, from dirt ovals, to major speedways and road courses, even drag strips.
I took the liberty of omitting anything that could not easily be verified as still open, so if you see something that is missing that you can guarantee as still an active track, feel free to drop me a comment.
I also plan on expanding this more than just North America, but that will take some time.
Have fun and get out there and see and / or participate in some races!
