Ohio, it is pronounced "ofn"

I miss blogging. Today, I was in the classroom of a very well qualified 6th grade reading teacher. One of the kids I was talking to while the teacher was out of the room said "ofTen". I corrected her and had to prove myself with the dictionary. When the teacher returned the students asked her to say the word spelled "O-F-T-E-N". What did she say? She pronounced it how everyone else in Ohio does, "ofTen". I would say 75% of MN, gets this right, but only about 2% of Ohio. Shape up Ohioans...
