To the best of my recollection, and I will readly admit my memory ain't what it usd to be but it seems like you must have a valid goverment issued drivers license in order to aquire and keep a competition license.
Now what follows is pure rumor and may not be worth the effort required to key it but here goes. "Spencer's state issued drivers license was suspended when he was found guilty of DUI. The Judge did make allowances for him to drive under certain situations so he could rehtain his occupation and competition license but not only was he drinking at fan fest but he was also drving a passenger car while impaired both of which were in direct violation of his probation. DSR (Don) felt he had no recourse but to terminate Spencer and report the entire situation to NHRA or place his team in possible legal jepoardy. Subsequently his drivers license was totally suspended which removed his qualification for a competition license".
That's probably not worth the time it took to key it but there it is. Had I not heard it from usually reliable multiple and separate sources I would not have mentioned it
