Gave my last lecture in our ethnobotany class (EEEB G4086) at Columbia University this morning. A full two hours on "Steps Toward the Sustainable Use of Plant Resources". And then a walk down 123rd to the subway station to get the uptown D train back to the Bronx. Nice day for a walk - and for bouncing around in a subway car. I ♥︎ NY. [NOTE: Still no visa letter for my upcoming trip to Myanmar. Sigh].
