I am headed to ocracoke in 2 weeks. We have not been there for a few years, probably 6, I do t remember having to purchase a pass to drive on the beach before. But I read about recently. Is it a year round thing? Both times we have gone in September. Maybe we were just clueless last time and didn't realize we needed one. But want to make sure we have one if we need one this time since it seems more enforced now.
