Idalia Days Celebration
Community members headed a project aimed at emulating the summer annual town celebrations of neighboring towns (i.e., Wray Daze). The event, coined Idalia Days, takes place each summer if enough interest is provided. During its inaugural celebration, Idalia Days provided activities and events in which the community could partake. Drawing on themes used in previous town celebrations, events include bed races, an old-time baseball game, old man six-man football, a melodrama illustrating the history of the towns relocation, and a fire hall dance. Fun is had by all.
Idalia High School Football
Due to low enrollment of the high school, Idalia, like hundreds of schools throughout Kansas, Nebraska, Wyoming, Utah, and Texas, plays six-man football, a variation of football involving six players on each side off the ball rather than the traditional eleven. To this end, Idalia has had an extremely successful program over the last decade and has become a staple program in Colorado Classification A 6-Man Football. The team won eight state titles between 1998 and 2010. Their most dominant team was the championship team of 2005.
