Bavaria is probably the most "German" german region. That's where all the lederhosen stereotypes come from.

Basically it's the Texas of Germany. Old school, religious, and conservative.

Edit: in the very rural parts, they even have their own dialect that to some Germans is almost completely unintelligible. I realized this when I took German language classes in high school in the USA and what they were having me learn was very much NOT the way my Bavarian mother spoke to me. It felt kind of irritating when they told me I was pronouncing things wrong and my grammar was wrong when I fuckin' lived there as a child and spoke it fluently.
