Why aren’t football stadiums in colder climates always designed as a closed dome?

Question

For example, when the Green Bay Packers built their stadium they had to have known it would constantly be snowing. Same with Kansas Citt Chiefs.

Answer 1

I imagine it’s more expensive to build an enclosed or closeable dome, and when it’s not that cold for the majority of the season, why bother. Plus football is a sport that’s almost always (from my knowledge at least) played outside, from kids to college. So it’s like a tradition or convention, or something.
