Typically yes its to Cr members, and when we have open slots we do give opportunites for others out side of CR. Sometimes the spots fill up so quick there arent really extras, this track day we have many open spots.
So if you want to invite some friends do so we would love to have them. Please though only invite people who will be respectful of other people and there property, and no hunk of junk thats going to shut down the track.
