Yes. We had a basic registration and made the banquet optional. It worked out pretty well as we had several that couldn't be here for the banquet due to prior plans, and some who didn't want to spend the extra for it.
I really think having those weekend events for those who can't make the weekday festivities is a great addition.
Oh, and I've been told my presence at the banquet is required so I'm in for this one. LOL
Also would love to help with the planning for the autocross/racing events.
