More stadium

In today's Times-Dispatch, Mark Holmberg has a column about the Diamond and the neighborhood around it. It's not bad for him (mentioning the homeless? Check. Bringing up blue collar past? Check, please. Misusing the term "begs the question"? Bad copy editors! Bad!), but it takes the estimable John Sarvay to tease out Holmberg's larger point: if a minor-league stadium is such a surefire economic booster shot, why is the North Boulevard area so grotty?
