The Pentagon is a modern 50s era basketball arena that was the brain child of Kelby Krabbenoft (yes, Joe Krabbenoft’s dad) when he was CEO of Sanford Health. Denny Sanford spotted him the money from his billion dollar money pot with the idea of luring major college marquee matchups and regional tournaments. ESPN signed on. Unique venue to watch a game.
It is also home to the Sioux Falls Sky Force pro team affiliated with the Miami Heat.
