RE: Kay's Ice Cream
Happy to say that the Chapman Highway Kay's is still with us. They changed telephone numbers recently and the internet's still got the old one everywhere. I updated Urbanspoon. Anybody Googling looking for them, their number is 865-659-4076.
Also found in Knoxville: a former Kay's location on Asheville Highway reopened a few years ago, run by a woman who worked at that Kay's in the 1970s, as Scott's Place. While technically not a Kay's, it has the iconic ice cream cone sign, and both Scott's and Kay's get their ice cream from Greenwood in Atlanta, so it's kind of close to being identical.
