Santiago, Chile - met a girl from my hometown randomly on the street. Very westernized city. It's like NYC's latin love child. Being on central time made it such an easy adjustment. Practice up on your Spanish though!
mountainous chile... Been from Iquique to Castro and everywhere in between. And going again!
