I am a driving coach for HOD, and have done many of their events.
You have different organizers up there than I do down here in Florida, but its the same deal. You should get a solit 1.5 - 2 hours of actual seat time with an instructor.
I highly recommend doing it. Any questions, shoot me a PM.
Florida, ay? I'm in Fernandina. I'd really like to hit the sebring event but that's kind of a drive from here. I'm really thinking about trying the Daytona one since it's about the same distance to there or Roebling but it's like 150 bucks more. Then again hitting those high banks is on my bucket list! They use the road course layout, right?
