Introduction 

"Stephens City celebrated its semiquincentennial, or 250th anniversary, on September 1, 2008. A large section of the center of the town, comprising 65 acres (26 ha), is part of the Newtown-Stephensburg Historic District, listed in 1992 on the National Register of Historic Places."

This paragraph in the introduction consists of two completely unrelated subjects. The 250th anniversary is already mentioned later in the article, so this sentence can probably be removed. The historic district sentence, then, could be incorporated somewhere else in the article. In fact, it is mentioned in the "20th century to present" section so maybe we can move it there. I will make these changes tomorrow if no one objects.

Also, as I mentioned in my edit comment, I think the word "semiquincentennial" should be removed. If a word is so obscure that you have to clarify what it means, why not just use the clarification instead? It looks a like a case of using a big word for the sake of using a big word. Again, I will make these changes tomorrow after giving ample time for comment. Thanks!
