I've heard great things about Grand Rapids, another pleasant town in an awfully mismanaged state.Yeah Washington's politics are terrible. It's better in Spokane but still hard to completely escape it like you said. Crossing the border into Idaho feels like you're actually free.
I like mid sized cities too. Boise is the best in the West. Colorado Springs is great too but in a similar situation as Spokane by being in a woke and gay state. Reno might be another option but I haven't been there. No income tax in Nevada and close to beautiful scenery.
Grand Rapids is amazing in the Midwest.
My personal favorite in the East is Knoxville. Beautiful scenery, friendly people, and TN is a small government, conservative state. Northwest Arkansas is also similar.
Unfortunately I work in a STEM field that tends to be concentrated in bigger cities. If I move to any urban area under 1M population, I'd largely be limiting myself to remote only jobs.
