Ted Drewe's Frozen Custard (St. Louis, Missouri)
Ted Drewe started selling frozen custard (his own concoction) in Florida in 1929. The ever-busy entrepreneur split his time between midwestern carnivals during the summer and Florida beaches in the winter, finally opening a permanent stand in St. Louis in 1931. In 1941, he opened another store in St. Louis along Route 66. Despite offers to franchise, the business has remained family-owned and operated. During the winter season -- a less appealing time to down a cup of frozen custard -- they sell Christmas trees.
