Heya Kat,
I recommend you try to get to San Fransisco and to Boston.
Boston's an underrated city with lots of things to do and, well, it's just a beautiful city. It can get pretty cold if you're not used to it. Try to see some baseball there (cheer for the Boston Red Sox if you want to make friends

)
San Fran is an awesome happening city. You've gotta see the Golden Gate Bridge, but it's kinda touristy. The real fun happens at night time! There's a great bar scene there and everyone's fun and friendly.
If you have any more questions I'll be happy to answer them
Cheers,
JohnnyB
