Reminder-Yes, the date is set in stone. The race will be set in stone when deposits are receieved per Bernie’s initial post in November.
The date is what was offered for the one and only time karts will be on the track.
I have family/frends that live all over Texas and have lived there myself. The one thing about Texas weather is you can’t predict what it will be, not this far in advance and barely a few days in advance! 8-)
