Since I have been to 6 continents already (to me, Australia and Oceania is the same continent), Antarctica is the continent I would like to visit. Visiting Antarctica is on my Bucket List.
Brazil and/or Argentina at Iguazu Falls in South America. Since I lived in Italy for many years and have a home in Colorado in the US so 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. [ Iguazuargentina.com Link ]
God's Own Country aka the United States of America, land of milk and honey, land of peace and plenty.
Personally I would like to go to Rhodesia, and go on a Hippo hunt.
