My dad told me about the sign, the rest I saw for myself.

...the rest of what you saw for yourself?

Sundown towns One time I asked my dad for more information about it, or to tell me more, and he said it wasn't a sign the city put up, but a guy that owned some land on a mountain on the edge of town. Eventually someone cut the sign down. It was a billboard sized sign. My dad was kind of old, he was born in the 30's. When, how long, the sign was up I couldn't say.

The link you gave is from an author's personal site who writes fantasy novels. This is worldbuilding for his Lovecraft Country) dark fantasy novel. The author of Sundown Town (James W. Loewen) writes about alternative and questionable history based around racism (he is a retired professor who taught about racism and social justice for 20 years in Vermont), and his claims seemed to be mostly vague and lacking historical support, choosing to simply look at things like census data to determine labelling a place as a sundown town. He also strongly dislikes current history textbooks because he feels they are too boring and believes the only way to teach history is to give students a social problem to solve rather than simply presenting what happened.

He wrote books about this, some being "Lies my teacher told me", "Teaching what really happened" and "Lies Across America: What Our Historic Sites Get Wrong".

Here is his website for your own checking.

All of this said, from the reviews I've read (after following from your link) it seems he was arguing that the majority of sundown towns weren't even in the south or places like WV, but in the midwest like Indiana and Illinois.

I believe there absolutely were things like this going on during segregation, and it wouldn't surprise me to learn about areas in the past like this. I just don't think your sources were cited well regarding this discussion.

From what you've said your father said in the past some landowner had a sign on his land and then it was taken down. That's entirely plausible, but I would say it's hardly something related or relevant to the state today.

Here's another thing: everyone in 8th grade in this state has to learn about the labor war as it was a critical history of the state. Battles like Blair Mountain were fought during a time of segregation, but in WV miners (making up the largest workforce) worked, fought, ate, and died together to fight the company owners, even with the Pinkertons (now Securitas Security Services USA) hired and the government stepping in on their side against the laborers.

The company owners tried to divide people by race and everything else they could in order to take advantage of them. This is something every WV student learns. We even have a test specifically for it with awards to never forget the history and the importance of unions and labor rights. Sometimes I feel like this is the only state that makes sure we don't forget that.
