No ProGRT next year? USAC putting more nails in gravity coffin?

I have heard some rumors that at least three of this years ProGRT venues do not intend to bid for a ProGRT next year following similar fate of other venues. Mainly saying that there is a lack of return on investment. How could you blame them. Go look at the main landing page of https://www.usacycling.org and see if you find any mention of mountain bike racing. Looks to be all road events to me. Isn't there a national ProGRT coming up? Wasn't there one that just finished? How hard to you have to dig to find info of them. Sad that USAC can not show mountain biking some more love. The challeneges behind the scenes as a promoter has not gotten much better from the looks of it.
