We stopped at Corbin, Kentucky for the night. This is the location of the first Kentucky Fried Chicken Restaurant. The place is still open and has a museum dedicated to KFC and Colonel Sanders. You can read more here.
We traveled through Indianapolis, Indiana and Cincinati, Ohio today. All of the trip was through smoky conditions. Only at the end, as we neared this location, did we start getting into clear air. We talked about how over the long term whatever elements are in the smoky air would precipitate out into the soil and onto the crops. The corn, the wheat, and all other crops that eventually become food products would surely become contaminated. We hope that the conditions we saw today were infrequent and not constant.
