In Southern California at the moment, but I'll be spending most of the next 3.5 years in the Northeast due to college. I'll probably come back here during breaks, but how often will be contingent on the internships I get.
For grad school and the early years of independent life, I would love to live in a vivacious urban environment, ideally in San Francisco, Boston, or New York City. Afterwards, a suburban area with some culture would be nice.
As for traveling, I'd love to go to Japan, France, and England. Might study abroad in one of those countries, but that'll take some serious curricular planning.
