Q. In the sentence “Cane Ridge post office in Van Buren County, Tennessee, was opened in March 1866,” the town name is Cane Ridge and it has a post office. Would you capitalize “Post Office” or leave it lowercase?
A. In your sentence the phrase “Cane Ridge Post Office” looks like a title that should be capped, like Cane Ridge High School. If you had written “The Cane Ridge post office,” then “post office” might be read as a generic and lowercased in the way that you would lowercase “the Cane Ridge gas station” or “the Cane Ridge bus stop.”
