EWWW!!! Caltech is so....weird?

I got admitted to Caltech and Franklin W. Olin College of Engineering (as you see, I am very interested in engineering). ok. reasonable. I just visited the two colleges, and I found the Caltech atmosphere so...weird. The students are different. weirdo nerds. The are so ...i can't explain. What do you think about Caltech? I thought its the nations best engineering college. I didnt like caltech so much, and I have decided to go to Olin College. What would you do?
