We posted yesterday that "At
approximately 1:00 p.m. today [Tuesday], a helicopter landing will be
conducted in Prospect Park and on Randall's Island."
The reason: "Prospect Park will be closed on Friday, October 25 from 12 – 6pm due to security associated with the President's visit." [The message on that website changed on Thursday.]
President Obama is coming to Brooklyn on Friday to pay a visit to the unique Pathways in Technology Early College High School (P-TECH) in Crown Heights. This is the school he spoke admiringly about in this year's State of the Union address, where students graduate "with a high school diploma and
an associate degree in computers or engineering."
