North Carolina definitly here on the east. You can have both mountains and ocean just a few hours away either place. If you love the mountainous area, Asheville is beautiful and on the coast, the northern Outer Banks has a northeastern coastal flair to it, while the southern part is like Myrtle Beach without the tourism. Nice. Going more west, Colorado is beautiful and a good place to find fairly decent jobs for the economy that we now live.
AliceBvB has a good point..Expounding a little would be helpful. How much $ would you like to spend on the move & do you have a job lined up? Wait! Wait! that wasn't your question!. If I were to pick any place in the world to live, I think it would be Fiji. If that wasn't available. Australia! In the U.S., I grew up in the Pacific Northwest, & emanuelblum is right it is Beautiful & very green! Rains a lot though. I would pick in the U.S. Key West! I had fun answering your question! Thanks for asking it.
