For vacation, southern California is my perfect place to visit. Not to live, but to visit.
I've always wanted to see Japan, though. I want to learn the language before I'd attempt to go though, and it's something I want to do years from now, but it is a place I've wanted to visit since I was a kid.
One day, I'd like to see Sweden, because my family is from there, and I'd love to see Europe, and what better excuse than to just have fun visiting where my bloodline hails from?
Outside of that, Canada as well, though I already intend to go there before the year is up.
If I had to choose a place to live, it would be Oregon. Lovely looking state, has majors cities but isn't really polluted and over crowded yet, and the Pacific Northwest just had a feeling to it that makes me feel at home. I would detest the constant rain, however.
