Is being part of tech scene a requirement? Chicago is pretty nice, affordable and cosmopolitan.
In other cities it seems like you have a single or a few employers and if it didn’t work out with them you’d need to uproot your life and move areas again. Having an ecosystem like that allows a bit more options.
That being said I don’t imagine Chicago to be like that, what tech companies do you like in that area? As that’s what I’m qualified to do.
