Terry,
You need to go to the NASA website and then go to the FL events. You need to be a NASA member.

And yes that is the track, i was in a Test and Tune a couple of weeks ago and you can hit abou 145mph on the straight away, i think for my car it was a bit better than gainsville, even though a bit riskier (walls ponds, etc) my car has no powersteering and i have pretty big tires so at gainville i was having a hard time turning the car in those little corners. Not that i didn't have fun but i prefer a bit bigger track.
