The normal V Saturday classes on Friday, V Sunday classes on Saturday with Sportsman, Nationals Sunday.
No, it's in between the V classes on Friday. I run longer than normal and pay the overtime to get everyone the same amount of track time (barring issues) as a normal practice day.
Figure 5pm gates open Thursday - depends on who has the track that day. Could be earlier. Practice I think will be $150 for the day if you're not racing that day (or for other bikes or whatever). If you are racing and want to run practice as well that afternoon it will cost you.
