Every aspect of the exchange experience is one that cannot be traded for anything. Studying in Boulder, Colorado for one semester was one of the best experiences of my life - my only regret is that I didn't stay for two semesters!
Nothing compares to the chance to study at another university, in a different country, living on campus, getting involved in the student life and having the opportunity to live in a bona fide university town.
In between studying, I jumped at every opportunity to see different parts of the US, organizing road trips and even making it to Mexico! I loved getting involved in the American college atmosphere, attending all the football games, celebrating Halloween, snowboarding in the nearby Rocky Mountains and experiencing my first white Christmas.
My academic experience at the University of Colorado even influenced my decision to transfer from an Arts degree to an Arts/Science degree when I returned to Gifu-city.
