I flew four hours from New York to Houston, Texas, spent 10 hours in the Houston airport, then flew another 10 hours to Buenos Aires, Argentina. I drove all over the city of Buenos Aires! I'm about to head to the airport now and fly another couple of hours down to Ushuaia, Argentina, at the southernmost tip of South America.
It's been a long journey from New York City (in North America) to the southernmost tip of South America, but it's not over yet!
In Buenos Aires, lots of people take motorcycles around, but I opted to take taxis most of the way. I also used Uber, which is not technically legal in Buenos Aires yet, so the drivers ask you to sit up front with them so they look like they are just driving their friends around!
I went to a place in Buenos Aires called Palermo. It's full of fun restaurants and shops, and at night on the weekends, you can really get a sense of how vibrant the city is.
