Same thing happened to my son, flew out of Virginia to Arizona and got a rental, had his picture taken too with a fine, except one thing:
SUPPOSEDLY THE FINE IS AGAINST THE VEHICLE OWNER FROM WHAT I LAST READ, AND WOULDNT THAT BE THE RENTAL CAR AGENCY, FORGET ALL THAT, DO LIKE I DID, I BOUGHT A PLASTIC COVER THAT HAS BITS OF METALLIC IN IT, THROWS THE FLASH OFF, PHANTOMPLATE.COM
