Customers were waiting 14 hours to order at a new In-N-Out Burger outside of Denver on Friday, as Colorado got its first two locations of the Southern California fast food institution.

The burger craze at the location in Aurora forced officers to direct traffic, which the police department described on Twitter as “double double animal style,” KTLA sister station KDVR reported.

The Aurora In-N-Out is one of two that opened in the state Friday, with the other in Colorado Springs. That location was slammed too, with the first customer having gotten in line on Tuesday, according to a journalist at a local paper.

About 4 p.m. local time, police said the line “wrapped around the mall twice” and was estimated at 1 1/2 to 2 miles long — and 14 hours.

“They will close before you get to the window most likely,” officers warned via Twitter.

Police encouraged people to support local restaurants that have no wait times.

“Maybe support another local eatery today and In-n-Out another day if traffic is too hectic for you,” the Aurora Police Department said.

All In-N-Out Burger locations are open daily from 10:00 a.m. to 1:00 a.m. and until 1:30 a.m. on Friday and Saturday, according to a release from the burger chain.

In-N-Out plans to open a total of at least nine restaurants across Colorado.
