I spoke with Alan Reinhart and, after some confusion, it actually IS posted. You just have to know where it is.
Here's how you find it. Go to NHRA.com. Click on "Schedules" in the main menu bar (the one that starts with "NHRA 101"). In there, click on "Full Throttle Series". That's easy, but this is where it gets tricky. You see the Winternationals? DON'T click on "schedule" at the right, that would be too obvious.
What you don't probably notice is that the "50th Annual Kragen O'Reilly Winternationals" is also a link. Click on THAT. It's a .PDF file with the detailed schedule.
