Jeffersonville, Indiana. Where I grew up. It’s not a suburb of louavul. It’s ...... Indiana. Separated by a body of water known as the Ohio River. Maybe you’ve heard of it?
Clearly there are differences of opinion on this.
Wife, who grew up in KY and lived in Louisville for a while off of River Road almost in sight of Indiana, says it’s a suburb.
It’s been part of the Louisville metro area since 1950 according to the Census Bureau.
