Dave, hope you can make it this year. Just make sure you sign up on opening day of registration. We sell out same day.
Did you ever get to swing by any of the events last year? I thought I remembered somebody in a blue 135i checking it out, mid-year last year. If not, still feel free to spectate and chill for a while there, and you'll likely be able to passenger with a few drivers. We even have loaner helmets.
