A chilly start today — only 49 right now. It’ll be partly cloudy and 64. Rain in the forecast tomorrow. It’s a big night for community activists involved in talks meant to end four decades of indecision about the Seward Park Urban Renewal Area. They’ll take part in the fourth of four mediated sessions designed to end the deadlock. Today we’ll have our interview with Brett Leitner, a new player in the old SPURA debate. Also today, an update on what’s happening with the victims of the Grand Street fire, six months after they were forced from their homes.
