Is that ton of money in 100 dollar bills or 1 dollar bills? Either way I wouldn't limit myself to one country. I would have a house in Switzerland and one in Greece. Oh, and I'd have a time share on the island that Jim Morrison, Buddy Holly, Elvis Presley, Michael Jackson, David Bowie, Jimi Hendrix, and Jerry Garcia are all hanging out on.
I'd have to go country shopping for a few years to help me make up my mind. With what I know now, I would pick Norway but I've never spent a winter there so I can I be sure?
