It's just opened up, I got that email about TrackDaze today. will add it to the calendar. Be careful though, Trackdaze needs 3 weeks notice for a refund, NASA needs 1 week. Weather can go either way as you said but you can't cancel with TD if weather is questionable.
My last event of 2011 and my SECOND event of 2012 involved driving to the track on my winter tires and changing to r-comps. Traction was...limited
