1. Go to USU sporting events.
Attending gymnastics, hockey, and basketball are all great ways to show your school spirit.
2. Sled down Old Main Hill. 
I am, personally, not a fan of this, but I have heard that it's fun. ;)
3. Build a snowman. 
It sounds cliche, but most of us need a childish release every now and then. Before Christmas break I saw a snowman on top of the junction. That's an idea...
4. Ice skating! 
I LOVE ice skating and everyone looks like an idiot when skating, so don't use that as an excuse. ;) The Eccles Ice Center is a great facility where you can skate.
5. Ski at Beaver Mountain 
It is a great place to go if you enjoy skiing or snowboarding and is near campus in Logan Canyon!
6. Crystal Hot Springs in Honeyville 
It is said to be an awesome place to go for a warm soak!
