I have a '90 Miata that I have owned for almost 20 years now

I am going to put it into ITA. Can anyone link me to the GCR? I have 13 years of catching up to do on the rules since the days I ran my Rx7 in ITA.

BTW if you're so inclined, you can summarize thirteen years of changes into a post my Wife would appreciate the time spent with her instead. LOL
