Vegas? Whatever were they thinking? The rest of the list makes sense, even St. Louis. My daughter lives in Portland. But Vegas is the least authentic place on earth.
I thought that too when it first happened. Not a place I would be interested in at all. But they landed in Henderson, so kinda away from the worst of it, and moderate on housing costs. There is a 5 year plan so don't expect to be there too long. They have easy access to a massive amount of entertainment options - have become little "social butterflies". And it is warmer there now than here...mostly.
Good jobs in technical fields. Short term, it kinda does make sense for them.
Last weekend, just strolling around before a show they were going to they saw Rob Schneider (comedian) - he was just walking around - chatted for a moment, and got a selfy. They see "stars" regularly - both in shows and on the street. Not a big thing in my world, but kind of exciting for younger people, I guess... They have enough contact to have understood for a long time that 'stars' are just regular people that others are willing to spend money to see, so they are pretty well grounded.
I still wonder about the St Louis contingent....
