Hey, Phillip, don't forget that the Rochester area also gave us Honey Brown beer and Pink Catawba (blech) wine. I try to explain the concept of red and white hots (aren't the white hots made from chicken, or are those made from pork too?) to people not from that area and they look at me like I have three eyes. Also, do you remember when the biggest competition for McDonald's was Carrols, not Burger King? I think maybe Carvel custard originated there, too, but I'm not sure.
I lived in Dayton, Ohio for a while, and bratwurst (or brat for short, pronounced brawt) is big there, and they do have red and white versions of it. ("Would you like a red brat or a white brat?") Not the same as white hots - more like Italian sausage. Then there's the famous Skyline chili, originated in Cincinnati. Really more of a spicy spaghetti sauce than a chili - they serve it over spaghetti and with shredded cheddar cheese on top call it a "three-way."
Here in South Florida, the regional tastes really have been brought here by people from other areas. There are a lot of Cuban and Jewish influences - the Cuban coffee will knock your socks off (it's like a triple shot of espresso) and you can throw a stone in any direction and hit a Jewish deli. Can't think of anything that originated here, though, other than the Boca Blonde beer made at the local Brewwzi's restaurant. We do have those coconut patties, I guess, which are like York peppermint patties except it's all coconut inside instead of a sugary goo.
