Wow, I would pick France or Switzerland. I love both countries, however, I need to throw in the Italian Alps even though I've never been to that area.
Could I live on Ile de France or whatever that island is in the middle of Paris?
If my monthly stipend included enough money for air travel as needed, I would live on Maui. But, I've lived on Oahu and I need to get away every 3-6 months or I get Island Fever. So, I'll have to go with Paris or somewhere in Switz, like Lucerne.
