Zmax is a National Event track, plain and simple. The weekly, or whenever else they run prep is irrelevant, because it simply doesn't matter to them. That track doesn't NEED to be open and racing to support itself. Bruton sure doesn't need the money.
Even if they DID run on a weekly basis, NHRA comes in and completely scrapes a track to bare surface and re-preps for a national event anyway.
The "traction twins" told me once that was the nicest surface they had ever prepped
