there's open practice (for karts, not us) in the morning starting at 7. the gates will be open anyway for people camping out, so you can get there as early as you want.
i have the track from 2pm till 10pm.
as soon as you're signed up and get a wristband, you can get on the track to practice.
racing will start at 4pm.
there will be a half hour break after the 1st heats are run, then the 2nd heats will run.
after the 2nd heats there'll be at least an hour of open practice, probably 2.
then the finals.
i won't have an exact schedule until the day of the race. i don't know how many people are showing up. i'd like to schedule a full day of racing, and get full use of the track, but i can't do that without a rough idea of who's coming.
and no, you don't have to be packed up and gone at 10pm, just off the track.
