Oh yeah it's not just Iowa.
But if you go into a bar in rural Iowa, those folks aren't Ubering it home.
'Culture' might be a strong word but people definitely grow up thinking it's normal.
Agree with this. The "culture" thing isn't so much the driving bit, everyone knew that was wrong......but certainly is the drinking. I grew up in rural Iowa and you would think drinking is how they breath. Fortunately, most of the time cabs or friends took them home. But not always.
