The track is fast and flowy.
Take advantage of the CRs to learn the line. Without any CR help, I think a lot of people settle into "U-ing" the corners at RRR but that's a long time at lean angle and there's a lot more track available to get direction. It seems like there's only a couple of braking zones but once you start using all the track based on a CR's example, you'll find you can get into the brakes a lot more.
RRR's grid marshal is great. I don't remember his name but I think he exercises good control. I don't have all the facts about the ambulance incident from two years ago (just that it was driver initiative, uncoordinated obviously) but my perception is riders can go to RRR with confidence about grid marshal control.
If you run regular pump fuel, you'll want to get your gas outside. Only pricey canned fuel is available inside and it's only open during short windows.
Walking your bike to tech is a reality.
Bring a battery tender. Despite warm days it can still get cold enough in the early mornings of March to sap an untended battery.
High probability you'll really enjoy the track!
