I wrote the promoter and the district chairman and received a reply from Robin Tesvich. He (or is it a she?) states that you could show no proof of residency, only a letter from a lawyer stating that you were applying for a Louisiana driver's license. That you admitted to only moving to the state 3 weeks earlier.
It was not a six month issue. Had you been able to show a utility or credit card bill with a Louisiana address, or even an apartment rental agreement, you would probably have been ok.
