And for those who wonder whatever happened to the old steel mills that dominated Pittsburgh decades ago but have long since been demolished, try this article. Maybe the Steelers will have to change their names to the Pittsburgh Brownfield Redevelopments? The Pittsburgh Subdivisions?
If memory serves, the Pirates were originally the Alleghenies, but they changed their name when other teams called them pirates for stealing their best players. Until this year, it had worked the other way around for a while. But time is circular, unless you root for the L.A. Clippers.
UPDATE: Wrong link before. Fixed. Sorry.
