There are many popular organizations on campus, as I stated before. Those are some of the most prominent organizations on campus, but there are many others, as well as intramural and club sports teams and other such activities. Our most popular TEAM on campus would undoubtedly be our basketball team. Basketball at Gonzaga is part of the culture. If you don't like basketball, good luck surviving at Gonzaga (haha, joking). But seriously, the games bring the entire Gonzaga community together as one, and that is an AWESOME thing to see.
Most of the students in the dorms leave their doors open so that people can come in and out and visit with each other. It is a very warm and welcoming atmosphere. Overall, I would have to say that the residence halls on campus are awesome places to live, because each one has its own personality and they are all very fun places to be.
If you're awake at 2 a.m. on a Tuesday, odds are someone else is awake and is willing to have a random late-night philosophical conversation with you or something. I am definitely a night owl, and often find myself up late at night, but I am never awake by myself - there are always other night owls roaming around. It's pretty great.
The party/drinking scene at Gonzaga is up for debate. Some people would say that it is pretty prevalent on campus, while others would say it's not really a big deal. I don't think it's really that HUGE of an element on campus, but I would be lying if I said that it didn't happen at all.
Fraternities and sororities don't exist at Gonzaga (besides Alpha Kappa Psi, our business fraternity, and a couple other academic fraternities), however, we have an organization called Knights and Setons which is probably the closest thing to a fraternity/sorority. There is a huge brotherhood/sisterhood that occurs with Knights and Setons, so it is fraternity/sorority-esque, but the students don't live together in a designated house or anything, and they are big on philanthropy.
There is SO much to do on a Saturday night that doesn't involve drinking, it's pretty insane. I would know, as I do just that, every weekend. I generally prefer to have Boggle game competitions with my friends, but we're nerds. Haha. Just trust me when I say that there is a TON of stuff to do on campus that doesn't involve drinking, and that's awesome!
Like I said before, there is always so much to do on campus, that leaving campus isn't required much, if at all. However, if you DO want to venture off of campus, the main downtown area is only a 15-20 minute walk away, and there is a trail called "Centennial Trail" that takes you directly from campus to downtown on a very scenic route by the Spokane River. It's really nice. There is a fair amount to see downtown, and we often have Broadway plays come to Spokane. That is a huge draw for students, as well as good bands/performers that come play at some of the venues downtown. But, for the most part, students prefer to hang out on campus.
