Not bashing Ohio, I was born there, but the cost comparison should include all the pieces. The CA ZL1 hypothetical work up included $5k in sales tax. Ohio has sales tax too. Just not quite as much.

As for CA, I have lived here since I was 12...50 years this year. I want a second home out of state. Probably keep a house here in CA too. There's no better climate than the coastal area of the southern half of CA. Unfortunately, it brings many negatives like millions of people and all the associated traffic, crime, tax, blah, blah, blah. The politics of CA are also a big driver for me to leave. But looking around the country, the climate and cultural amenities (attractions, restaurants, etc.) are not found anywhere else in one package. When it boils down, it's all about each individual's quality of life, and that is primarily driven by your financial situation.
My wife retires this year and I'm probably right behind her. We are very fortunate to have made a great living as aerospace professionals and have great nest eggs individually that allow us to live about anywhere in the country. We're still discussing where, it may be more than one other place, but we agree we will keep a CA home. This being a car forum, car guys know that CA is the Mecca of the automotive world. I see more exotics and customs everyday than are probably in the state of Ohio. So, there are pluses.
