A cool March wind greeted me this morning as I walked to the train, briskly coming off the harbor and up past the lofty old buildings downtown. And yet, it was an unseasonably 58 degrees... no coat necessary. After a week in Lake Tahoe under a blanket of five feet of fresh snow, this early spring is a bit shocking to the system. Confused New Yorkers lined the subway platform, either overdressed in too many layers or underdressed in a threadbare teeshirt. Give it a week or two and we'll figure it out. Pale Male and Lola certainly have: a new nest has been announced by bird watchers, a ritual that marks spring as much as the budding trees lining the Hudson or the St. Patrick's Day Parade next Saturday on Fifth Avenue.
