Ben is correct regarding blind permits in DARE and CURRITUCK counties possibly some other counties in NC, the county offices licenses permament blinds and boat blinds, and will only issue a few new ones each year, aside from all their renewals..this effectively limits the numbers of people who can legally hunt in the waters around the county, protecting the local hunters from outsiders. Some years, they don't issue any new permits at all.
It is impossible, for all practical purposes, to obtain a blind permit in DARE or CURRITUCK. Generally speaking, one must inherit a blind or know somebody who will transfer their blind permit to you.
that's how it works.
