I lived in Utah and SoCal for about half my life. I had family in Vegas for a decade.
I think Vegas is going to be a pretty bad baseball town after a few years. It's not that big, there are a ton of transplants, a billion things to do, and filling a stadium 81 times a year will be a challenge.
I still don't understand why teams aren't aggressively pursuing the Carolinas. The population is massive, it's rapidly growing, and there aren't any baseball teams that are particularly close.
