I’m not aware of any New Years Eve activites sponsored by the U, but I do recall activites like this at past bowls. Perhaps they are still in the process of organizing them.
The UofU alumni Association is sponsoring a tailgate prior to the game, at the Rose Bowl (probably actually just adjacent to the Rose Bowl on the golf course). I purchased tickets through the alumni association, as a result of getting an email from the Crimson Club. I don’t have the emails anymore, so I can’t point you directly to anyone, but I’d call either the Crimson Club, or the Alumni Association.
They are a bit pricey, but for me, this is a bucket list activity, so I’m spending whatever it takes to get the most out of it 🙂
