Howdy—earlier this year my wife and I moved to Logan from Provo/Orem. Before then we moved from Oklahoma in 2020, so I can relate to being from out of state. The LDS church is very prevalent in Logan, but it isn't as "concentrated" as Provo/Orem, where it is nearly impossible to find friends if you aren't a member of the predominant faith. Here in Logan, we've found that the LDS members are far more tolerable and friendly here. But the occasional invite to a service or holiday bash at the local ward may pop up from time to time. My wife and I have declined these, and it really hasn't caused a fuss among our neighbors. All is generally respectful and cordial.
However, I will say that there are some LDS folk here who will be friendly at first, but once they discover you're not a member, they won't interact with you. Not a huge deal to us, but that is a thing to be aware of. An example of this is when we moved to Logan, we had some upstairs neighbors come down and bring us brownies as a welcome gift, but when they quickly realized we weren't Mormons, we never heard from them again until they moved out. Brownies were good though. lol
Not sure what flavor of Christian you are—my wife and I are Christians as well—and we attended Alpine Church (nondenominational) for a bit, which was lovely. However, we are now members of St. John's Episcopal Church and have found an amazing community there. If you're on the moderate side, politically speaking, St. John's may be a bit too liberal for your tastes (ordained LGBTQ ministers, etc), but you're more than welcome with us on Sundays. There's a social coffee hour after every service, book clubs, etc. I do know some folks who are starting an evangelical church plant in town if you'd like their contact info. The lead pastor and his wife are good people and they host a Bible study in their house every Sunday.
Advice: Get involved in an outdoors group or club at school. USU offers every outdoorsy activity under the sun, which is a perfect way to make friends and build a network. Don't isolate yourself and try to go out of your way to make friends. I'm confident you'll find some good folk to surround yourself with.
There's a good chance my wife and I are older than you (early 30s) but if you're interested, we're totally down to connect when you get in town. DM me if you're interested or if we can be of service.
Good luck, OP!
