If you've never experienced upper Midwest winters, you'll be in for an interesting experience.
Also, not much in the way of topology, contrasting with SoCal.
I grew up in Chicago and got out of the entire area as soon as possible, due to (in no particular order) allergies, weather, and seasonal affective disorder.
I live in SoCal now and love it here, but climate change will probably force us elsewhere within 20 years. We already spend most of the summer somewhere else to escape the heat.
