instead of Zion. Utahns probably say the name of the bank a LOT more than the name of the national park. I never noticed Zion/Zions until I moved to California and realized that everyone said it without the "s" — then I looked at the park name and realized they were right.
And yes, all my California friends call it "Zeye-ahn" and I now call it "Zeye-uhn"
