And the answer is...

B: scenes from a movie were being shot. I got an e-mail the other day saying that a helicopter would be flying over Drew Univ. in the morning to film scenery shots. However, I received another e-mail in the afternoon stating that there had been technical difficulties and that they would be filming again at dusk. So, I tried to make myself present. I almost forgot: the movie is The Incredible Hulk (perhaps a sequel to the first?)
