Cassoday Kansas: known as the "Prairie Chicken Capitol of the World", this Butler County town is home to about 125 souls. From April to October each year, the first Sunday of the month, the town's population explodes as bikers pull in to enjoy the Cassoday Bike Run. Started back in 1991 by a couple of bikers that asked the café owner if she would open up on Sunday morning once in a while for bikers cruising along the Flint Hills Byway (Hwy 177), this monthly event has grown each year. Thousands of bikers show up for food, friends and entertainmen each month. Located at the south end of the Flint Hills Byway, the Cassoday Bike Run is a terrific way to start your day on the Byway.
