When I think of the Green Line, I think of my old cassette Walkman. One morning in the early Nineties, I remember standing at the 47th Street stop waiting for the next train. At one point I ejected the tape, and as God is my witness, that cassette flew straight to the rooftop of 316 E. 47th street, which is located right under the ‘L’ stop. I didn’t make any attempt to get it back, either – I purchased the tape in a bargain bin for $1, so I just went back and got another copy for the same price. But I was more fascinated than anything by this impromptu physics lesson. I had no idea that the eject button of a portable tape player had that much velocity. So if anyone ever found a Flamin’ Groovies tape on the roof of what is now the New York Deli, now you know why.
