Denver is a boom and bust town. Every once in a while, it thrives for a decade, then busts with an exodus of people (myself included). It will rebalance and boom again.
I left because I was sick of having to weather the storm of boom and busts, saw $250,000 homes become $950,000 homes (no change to the home itself) and prey upon the young people moving there to ensure they are financially burdened with Boulder Boomer retirement plans.
