4 seasons. Two not bad, two Hot and humid. Bring your bug repellant. Can be flooding and Tornados. Remember Joplin? Was devestating. Big cities (STL KC) big crime in designated areas. Black ghetto, avoid if white. Yes the truth hurts. White ghetto too.like anywhere, nothing is perfect. STL county has extremely nice towns. Kirkwood, Ladue, Chesterfield etc. But costs are high to live nice.
