Soda vs "Pop"
I think this is a fascinating map. It shows regionally in the country what terminology people use to reference soft drinks. Growing up in New Jersey, we called all types of soft drinks soda. My mom's family are from Buffalo NY. As a kid, going to visit, I was confounded when everyone referred to soda as "pop". Looking at this map, you can see the state of New York divided almost directly east/west of the Finger Lakes region. There are other curious demarcations nationwide as well.
