The Colorado State Fair must go on: What to know about 2021 event

What to know: Fair organizers estimate that crowds for the 11-day event will reach near 2019 levels, when more than 466,000 people visited the grounds. "Tickets are selling super well," said spokesperson Katie Richmond. "We are glad to be back."

• Colorado public health officials are encouraging people to wear masks indoors and outdoors where social distancing is not practical.
• No proof of vaccination is required to attend the fair as the state pursues an optional approach, despite increasing evidence that mandates are effective tools to boost immunizations.

The other side: Instead, state health officials will lure fairgoers with gift cards and other incentives to visit a vaccination clinic on the fairgrounds on the weekend days.

If you go: The schedule is packed with down-home fun and crazy food. Here are three can't-miss events:

1. Food truck competition on Aug. 31: Five food trucks (including two from Denver) will prepare two dishes and compete for fan favorite and the official "governor's plate" award.
2. World Slopper Eating Championship on Sept. 4: This sanctioned eating contest will draw the nation's top eaters, who will try to consume as many sloppers as possible in 8 minutes.
3. Swifty Swine Pig Races, each day: What motivates a pig to race? Oreos, of course. The sight is sure to make you squeal.
