Pre-registration has actually been open since the beginning of the month. Lots of people are signed up but there's still a lot of people I know will be there on Saturday and they aren't yet registered. If you want to donate $50 to the club for not pre-registering, go for it. You can do the whole season and it won't cost you a dime until race day. Not sure what classes you'll run? No matter; pick them anyway. It's easier for me to delete an existing entry than it is to make a new one. Just don't double-click on the Submit button. It doubles up the entries.
