The first two weeks I was here, my morning commute took me roughly 30 minutes. I would jump on a 2 or 3 train down to Times Square, walk to the Port Authority station, and take the E train to 53rd St.
There was a problem with this, however. Living in Seattle for so long, your body becomes acustomed to the sea air. The breezes keep the humidity down and fall tends to be very crisp early in the year. In New York though, there is no benefit of a breeze (most of the time). Especially in the subway. It can be 60 degrees in the train, but because of all the bodies and lack of air circulation, the humidity skyrockets. It does take a while for your body to adjust, but I was beginning to hate the morning commute. I looked all around the train and found to my shock that I was the only one sweating at 7 in the morning.
So instead, I decided to walk to work through Central Park. Its about a 60 block walk, which takes me just under an hour to do. I have to get up a little bit earlier, walk the dog a little shorter, but I feel that its worth it (at least until the snows arrive). Its great - I get out of the city, walk through the trees, look at monuments and statues, gaze at ducks on the pond, and grin at the various outfits that people in New York force their little dogs to wear. Best of all though, is I walk by the seal tank in the Central Park zoo, where every morning the seals nap just outside the water.
So yeah, it takes me 20 minutes longer and my commute time isn't that much improved from the horrible traffic in Seattle, but shit - I walk by seals on the way to work. I don't know why more people don't do this.
