Today marks my 100th day of riding Metro-North.

Some observations:

* I used to get really annoyed that it takes so damn long to get from 125th Street to Grand Central.

I still do.

* For reasons I can’t really explain, I’ve never slept on the train during these hundred days. Maybe tonight.

* I wish I lived closer to the city, but I’m dealing.

* I have early-onset O.Seat.D.

* Slippery Rail season is deplorable, and was a really bad way to start your commuting career.

* In all seriousness, amidst all my griping, the commuting experience isn’t that bad. Across 100 days, I’m yet to see a drunken asshole, a truly filthy car, or a hint of vomit. (Of course, I’ll probably get the hat trick tonight.) A train car is sort of a microcosm of the New York metropolitan area: There are a lot of us, and not a lot of space. It’s only going to work if you’re mindful of your neighbor every now and then.

Granted, there are the loud cell phone talkers and the clods who feel their bag deserves its own seat. But all told, people behave pretty well.

Five months down.

Thirty years until retirement.

I’ll be posting more throughout the day as I reflect on my first hundred days. Feel free to share your commuting observations too.
