The best chili cooks will gather in Owasso today for the International Chili Society Oklahoma Championship cook-off. The winner of the ICS competition at the Harvest Festival Cook-Off represents Oklahoma at the ICS World Championship Cook-Off. Plus, scores of local teams will be vying for People's Choice and Best Booth/Showmanship honors. Read: Purchase a tasting kit so you can help decide some of these awards and sample 60 chili recipes at the same time. The cook-off is held in conjunction with the City of Owasso's Harvest Festival, which features bounce houses, hay rides, kids' games, a scarecrow contest, costume and pumpkin carving contests and lots of fair food and drinks. The festival is free, and so is the parking, which can be found at Owasso High School (12901 E. 86th Street North), where there will be shuttles running to the festival throughout the day. The chili cook-off runs until 5pm and the harvest festival until 9pm.
