NHRA and IHRA web sites list the tracks that they sanction. But there are dozens of outlaw tracks. I know of atleast 4 in North Carolina. There is also one in Maine. Winterport Dragway. It is a nice track. Great people.
In a seminar a few years ago Bret Kepner said there were something like 26 in Mississippi alone.I have tried to find a comprehensive list for years ,they seem to open and close frequently.It looks like some computor genius would start a website that everyone could add to ,shouldn't take long to uncover most of them.
