) We boarded a flight from Orlando, Florida to Buenos Aires in Argentina. We would board a ship that would take us from Argentina to the remote Snow Hill Island in the Weddell Sea. Mom slept for the whole plane ride, but I stayed awake and researched penguins that live in Antarctica on my phone. I hadn't realized how many penguins didn't live in cold areas like Antarctica. There was a boy sitting across the aisle from me. He was reading a book about sharks, which was pretty neat.
