Los Angeles, California. Love the lifestyle here.
New York, New York. Love the lifestyle there.
Plus I know people there, and yes I have experienced both for a good amount of time. New York for a week at various hours a good 72 hours walking the city. Los Angeles every weekend.
The Best Place To Live Is: British Columbia
Because: I live there, and it's a very nice place to live because of the multiculturalism there, and the beautiful fresh air. There's not "too much" of a city atmosphere, and nice people too. Whistler ftw.
