Update:
Went to our renewal appointment. They run you through in groups, there were about 9 or 10 all there for renewals. They pickup you paperwork packet when you arrive, check it and highlight where you have to print your name or sign. Then call you back as a group, and page by page step through where to print/sign.
Hand out a page on reciprocity with other states, cover a few basics such as it will take 90 - 120 days to get the new permit, but our current CHP will be valid after it expires, but only in NC. Also can't be used for purchases after the expiration date.
We were probably in the Sheriff's office, actually the ID Department at the detention center for 10 minutes tops.
