Riding the Harlem Line in the fall… it is sort of like this (in case you missed it on twitter last night):

In fact my ride home last night was quite a lot like that. We are in the season of falling leaves, and slippery rails. By all means most seasoned train riders are familiar with this phenomenon. But if you aren’t, every year Metro-North always puts together a nice little explanation about it. Just make sure you don’t add to the problems by throwing your banana peels and/or foil-wrapped lobsters on the railroad tracks.
