We are partially there. Events after July have to wait for the NFL schedule to be released though.
Don't worry, you can always register at MotorsportsReg.com, even if you don't think you'll make it. As long as you don't pre-pay, there is no harm in registering and not showing up. In fact, we'd prefer it that way, just because it makes things go faster/smoother at registration if you are already in the system. Plus, we do everything possible to avoid conflicts.
