For me the first place would be any or all of the countries bordering Iguazu Falls in South America. Since I live in Italy and have a home in Colorado in the US, I've already seen a lot of Europe, North America and the Caribbean, but have never been to South America although I've been close enough to see the coast of Venezuela. I particularly like waterfalls and Iguazu looks spectacular.
I would also like to visit the tiger temple Wat Pa Luang Ta Bua in Thailand, Denali National Park in Alaska, the Fiordland National Park in New Zealand, and the Monteverde Cloud Forest in Costa Rica. they all seem like beautiful and interesting places.
Japan, Germany, England, France :)
Mostly anxious to visit Japan or Australia. Hope it will be soon :)
Hong Kong a great and exciting place. www.DiscoverHongKong.com
