In a story about Prince George’s County’s emergence as the top producer of basketball talent in the country — Kevin Durant, Michael Beasley, every worthy Hoya and scads of other blue chippers came out of PG — I called the county “Ward 9.”

That’s a nickname for the county I’d heard forever — it’s been showing up in City Paper stories for at least 13 years. But a reader going by “Mos82” ranted in the comments section that nobody who actually lives there dares use “Ward 9,” and that referencing the county as another DC neighborhood is insulting.

I meant no disrespect. But, a simple Google search would have revealed that Mos82 ain’t the only one bothered: The Urban Dictionary calls “Ward 9” a “derogatory reference” to PG.

I thought PG enjoyed being thought of as part of the city: I don’t remember hearing any county natives complaining about the Washington Redskins, Washington Capitals, Washington Bullets using the city’s name while calling PG home.

And even one of the top AAU teams mentioned in the story, the PG-based DC Assault, wears its ties to the city on its chest.

But it appears I was wrong. So, why so touchy, county people?
