They might winter in Portland or even LA.

Spokane is another city in that area with a huge homeless problem, and perhaps even harsher weather (Boise is at least high desert). Though housing can be super cheap, my granddad used to run what we thought became basically a flop house that we nicked named the Empty Arms.

SLC seems to have focused more on housing the homeless, but even then I think in recent years they’ve found that their success has mainly just led to a larger problem.
