Add to that most of West Virginia, Tennessee, Georgia, most of Florida, Arkansas, Missouri, Nebraska, Iowa, New Mexico, Utah, Nevada, Washington, the New England States except Connecticut, in fact, the large majority of Catholics are not within an hour’s drive of any Latin Mass whatsoever.  Most aren’t within two or three hour’s drive.  Traditional chapels of different types seem to be located in little clusters, along with Diocesan Latin Masses.  If you don’t live near one of these traditional clusters, you can go to the novus ordo or pray at home.  

I think this set-up is a minor factor in children from trad homes leaving the Faith when they come of age, especially if education, job, marriage, or military service entails a move to a traditional Catholic wasteland.  I had a friend, RIP, whose son got married and had to move to NC for work.  The only time he and his wife + four grandkids go to church is when they come back twice a year to visit grandpa.  They’ve joined the vast majority of Americans whose religion is “not religious.”
Before and for a year after marriage, they were going to the SSPX chapel where they got married.  The oldest child was baptized there.  His wife, though from the novus ordo, (she didn’t go often) was seriously considering getting confirmed.  She went on a retreat and loved it.  But then “Dom” lost his job, the unemployment ran out, she was pregnant and on bed rest.  They couldn’t afford to stay in the second or third costliest area in the U.S.  They had to move away.  For a month they lived with her sister, her husband, and their three kids in a two room HUD apartment, illegally.  
Unfortunately, they did not continue to practice their faith once separated from a Catholic community and family life.  As you say, in most of NC, if a person goes to church, he is some variety of Baptist.  Now, they’re nothing.  The youngest three haven’t even been baptized, much to Grandpa’s distress.

One of the surest ways to remain without the Mass and the sacraments, is to go to the Novus Ordo.
