Have you ever been to Port Authority? It's gross and weird.
If you're traveling to or from NYC, I highly recommend taking literally any other form of transportation besides a bus that pulls into Port Authority Bus Terminal. Train, car, Segway, camel, even walking across the George Washington Bridge would be more pleasurable than spending time in Port Authority. Some parts of the Port Authority smell like a cigarette that was lit in 1979 and has been burning ever since. And I'm pretty sure all the farts from Times Square are pumped directly into the bus terminal on 40th Street & 9th Avenue.
Once in 2004 I was waiting for a bus to my parents' house and two kids were running around. They were dividing their time evenly between chugging Mountain Dew, eating Cheetos, and darting across the terminal. I kept thinking "one of these kids is going to puke," and then one of them did. A man came to mop up the vomit with a bucket full of water that looked like it had never been changed. I thought to myself, "I hope no one goes near that spot," and then I witnessed both kids sit directly on the former puke-spot and start playing with dinosaur figurines.
