The registration will be open a month before the event.
The practice registration is at the track in the morning before 8 am because it has nothing to do with SCCA but the track management. Sometimes you could register through the link SCCA supply or just through the track website.
I do not like websites they created by young or people who do not understand clear which info is important and priority of events but for sure the SCCA website is a multi colored jungle with a lot of puzzles. For a novice it’s a headache.
