I'll bite (but not into the whale shark!).
Agreed on the two homes bit... summers can get really hot in places where winter is gorgeous, and winter can get too cold in places where summer is great.
Summer house in Sweden; the food is great, the language is great, the people are great, the girls are great (don't tell my wife I said that), the cars are great, the music is great... you get the picture.
Winter house on Yakushima island, Japan. There are hot springs along the beach, where waves will gently crash over you as you relax. There is a moutain inland that is covered by 1000-year old trees, and the people are great. Great camping, great hiking, great girls, great nature, great baths, great people... again, you get the picture.
However, my ultimate dream home would be a 45-foot yacht, such as this:http://www.huntermarine.com/Images/M...C/45CCHead.jpg
That way, I could roam the world at will, discovering the wealth of wonderfulness around the globe. I have had this dream since I was a kid, and have spent many long hours plotting courses, studying countries, playing with languages. Even if the dream dosn't come true, it will still have imapcted my life greatly from the abundance of things I have learned just researching the possibility.
