The Greeley Stampede is coming up, and you know what that means. Corndogs, cowboy hats, concerts, and cars. One of the best parts of the 10-day festival is the demolition derby. Hundreds (yes, hundreds) of drivers will partake in the destructive chaos. This year's demolition derby will take place on July 7th at 2:00 PM, and tickets cost $20-25.
