I found some (I thought) useful resources for just about anybody interested in autocross (and other racing info), wherever you live in the USA. I have yet to look at other, more international sources…
The image below is the starting point for the NAAM (North America Autocross Map).
Here is another list of Regional Club Information, for autocrossing all around the country. Unfortunately, many links are broken…not good.
Some time back I found this racetrack (& other racing resources) site – . Its a great collection of worthwhile information; you could spend hours, here at the North American Motorsports Pages.
Quite a good bunch of helpful information to get you better Racing Ready!
