I know that feeling. Sounds familiar...
Okay. So I don't live in the US. Forget that all my stories are based there, but really, I don't know squat about picking and deciding which college/university to go. We use a whole different system over here,
That being said, I know a few things about you and what you should do.
Your (our) type of person, most times, doesn't know what he wants until he finds it. You could never decide on a college without a strong external stimulus to choose a particular one.
The first step would be out lining what you want. Then out line what you have. And then decide based on what the things you got can get you. You like Arch, fine! Stick with it. Find people who are studying it and ask them. About their school, and the course.
At some point in my life I wanted to be a surgeon. But after talking with a few medical students and a surgeon, I realised that although surgery was pretty cool, I can't do it. But then I talked with some other students studying what I am reading now, and I thought, now, that's for me!
It helps to know where you are going, but it's even more important to know the right road to that place. I'm glad you've posted this here, lots of learned people will give you valuable advice. Lots and lots. But in the end, what will really matter is what you mind decides up.
I know these wasn't very helpful, but...
