My first time in the United States was NYC. I never thought about it, but in the plane I thought to myself "Heh, NYC is really close to Canada". We arrived at JFK at like 3:30 am. My first experience was the huge line at the airport customs, like 1,5 hours of waiting. American flags draped on the walls and NBA on the televisions that were hanging on the pillars. A really big black woman looking extremely pissed off shouting the number of the desk you needed to go too, and when you misunderstood her and asked for reaffirmation, she gave you the evil eye. I forgave her though, it was 4 am. And on the road from JFK no NYC I was surprised at the quality of the road, holes everywhere.
I was on a sponsored trip so it was 5 days of waking up at 9 am and going to bed at 2 am while walking through NYC all day so it was kind of overwhelming really. Boat trip on the Hudson, going to NYC university, Times Square, the view at the Top of The Rock (and that elevator), watching a musical on Broadway, eating pulled pork hamburgers as breakfast, freaking ferris wheel inside a store, walking through Central Park, going to the American Museum of Natural History, our hostel giving shelter to Mexican immigrants sleeping on couches, 9/11 memorial, visiting the New York Surpreme Court, I could go on. All I could think of during the trip was "I'm actually in the US, wow, I'm in NYC, I'm actually in NYC". All I can say NYC is fucking awesome and I want to go back someday. And everyone in NYC was really nice, no issues really. And damn you got some big rats in the metro.
