just moved back to Atlanta from SLC where I lived for 6 years and still go back about once a month to ski/play outside and conduct business
I think SLC would kill it in the NHL... outside of the outdoor community there isn't really anything to do in the Metro Area during the winter outside of Jazz games.
Tons of transplants and the ski demographic/hockey demographic has a big overlap.
Tons of disposal income- Sightlines at Vivint Center aren't great but it/Maverik center could probably serve as a stopgap solution until a new Arena would be built- Sandy/Murray/Draper area would be best.
Would immediately become my fav team in the NHL
