Prospect Park in the 70s was, we're told, a shady expanse of drugs, mugging and murder; the savvy Ms. Thomas (and, perhaps, changing economic conditions in recent decades?) oversaw its transition back to the hub of Brooklyn life we all know and love and drink semilegally in when it's nice out. Prospect Park boasts nine million annual visitors, versus less than a quarter of that number in 1980. (Though Thomas notes that the Ravine remains "the park’s pronounced color line, dividing white residents from Park Slope from black residents who lived to the south and east of the park".)
