I see you like fireworks.
You should come to my city at year's end, "the skies over Guayaquil have been iluminated" because everybody burns the old year and welomes the new one. I've heard about many celebrations in South America that look really interesting and exciting. I just did a search on Guayaquil and found some really nice pictures - that's a beautiful city.
However, I've never been any further south than Cancun, and am terrified of flying over large bodies of water. (I have to fly to Europe later this year and am NOT looking forward to it)
