Rowan County Wildlife Club is hosting the sectional in September, they do a regular monthly match as well. It's not far.

I believe there are also some indoor matches in the area around Lake Norman, not sure if they're sanctioned.
Unfortunately something happened to the Statesville match, I got interested too late, but I hear they put on a hell of a match, currently looking for a new range.
Someone tried at PHA, but there was some miscommunication and I kinda doubt another attempt will be made there. They do have a nice unsanctioned pistol match, but it sure ain't USPSA.
Spartanburg, SC isn't too far away, they do two a month. Blackstock, in York, SC isn't either, not sure what sort of schedule they run.
