Once again, a fellow poster points out the variety and complexity of pronunciation in this great, huge, wonderful country.
At least twice a year my parents packed us into the car and drove us to new destination points in other states.
As kids, we giggled at all the different accents, and the way people pronounced everyday words.
We'd talk with people each time we stopped the car, and we practiced talking as they did. The adults would laugh (with us) at our attempts to imitate their pronunciation. We also learned they thought WE sounded funny too.☺
BTW, door-uh-buhl is an acceptable pronunciation.
