There are quite a number of places that I've always wanted/dreamt of visiting in my lifetime:
Germany (for its profound history)
Amsterdam, Netherlands - it would be cool to visit, have heard so much about that place.
Thailand - for their historical background in art.
Rwanda, near Congo, South Africa - that place has kept my attention riveted for a long time. Not sure if many of you know about the story about Dian Fossey and the lowland Mountain gorillas back in the early 60's to mid 80's. (Movie was made - 'Gorillas in the Mist' with Sigourney Weaver and Bryan Brown)
Japan - most of my blood relatives came from Japan. My father's mother's mother was born in Japan and emigrated to USA. My dad was born in an American-Japanese camp during the peak of WW2.
New Zealand - I only landed in NZ for an hour at 5am in the morning during a stopover from USA to Australia in 1998. I'd love to go back to NZ and explore the country some more.
Fiji - it's a tropical island near the clusters of Papua New Guinea, Malaysia and Singapore. (between Australia and Singapore) Fiji's east of Singapore (near where Tasman Sea meets Pacific Ocean)
Just about everywhere in Europe! Spain, Italy, France, so on!
