Hello!
I’m kind of new here, and just kind of looking around, getting familiar with this website.
I, too, attended (and graduated from) Northern Illinois University. I was a “non-trad” commuter student there, and when my schedule allowed, I attended daily Mass there. On weekends, I attended Mass at my home parish, where I’m an usher & EM, so I never got to St. Francis (the Newman Center) for weekend Mass. As GMarie offered, it was quite a vibrant faith community, and when I was a student, we even had a married priest (an Episcopalian convert, I believe) which sort of rocked me back on my heels at first.
Back to the topic: From our researching when our sons sought out schools, most large public universities have some Catholic-affiliated organization like the Newman Centers; Western Illinois U had one, and so did Illinois State and U of Illinois. The Catholic Universities usually had an integral Catholic faith organization.
Regards,
