Replying to Colorado State University

I searched and theres a couple other threads on this but im gona make this one anyway. I am a senior in high school right not and i just got accepted to a few schools in colorado(i live in pa) and right now i am leaning towards CSU. I was just wondering if anyone goes there and could tell me anything about it.  I am going to visit it in January but i just wanted to know from some people that go there if its a chill school,hows the parties campus life etc etc and also what would be the closets mountain to it.

Just any info in general on the school would be great.
