There was recently a thing on TV that showed the commercial manufacture of dogs, and they pointed out how different the recipe was for each region, that the dogs here in Cincinnati will have a wildly different set of spices than a dog in New England.
I can verify that, as we just spent some time visiting the wife's family up in Connecticut, and I had several grilled dogs that were a revelation. Full of flavor, where ours here in town are really bland and uninspiring.
It's odd, as Cincy is a meat kind of town.
I think I'm going to try to make some franks simply to try some different, spicier recipes. Now I just need a smoker...
