Well, 6-10 are still mostly true! (born in Florida, lived in NC and now Alabama).
Number 4 is true. It’s called the High Wall. If you are not part of the good ole boys network, you will not find a job regardless of how qualified you are.
Both my wife and I dealt with that when we moved to Texas. Now the head hunters and companies that blew me off 6 years ago now send us Christmas gifts and call me once a week about a job.
I smile at them, thank them and say bless your heart.
