AURORA, Colo. -- The Rocky Mountain Airshow turned away would-be attendees midday Sunday.
It happened after massive traffic delays Saturday frustrated many, causing some to park their cars on the side of the road to catch a glimpse of the Thunderbirds or walk up to 4 miles to the event.
The event marked 18 years since the Thunderbirds came to Colorado.
Aurora police began routing traffic away from the west side of Gun Club Road on Quincy Avenue around 11:30 a.m.

Airshow organizers said they did not oversell tickets and that the problem was the attendees were trying to get into the airshow at once instead of spread out throughout the morning.
Unused Saturday tickets were valid for the Sunday show.
Anyone who was unable to use their ticket is able to receive a refund by emailing the Rocky Mountain Airshow organizers at firstname.lastname@example.org with the name and email address used to purchase tickets.
Refunds might take a week or more to process.
Organizers opened parking at 7 a.m. Sunday, an hour earlier than planned, in anticipation for heavy traffic. They recommended attendees to take alternate routes to get to the event and to try to get there as early as possible.
In all, 22,500 people attended the airshow Saturday and 32,000 on Sunday.
