Bay Area residents may remember when cult favorite In-N-Out first ventured north from Southern California. The long lines! The tantalizing aroma! The late-night hours! The relentlessly perky employees!

Practically overnight, we became In-N-Out experts.

Now it’s time to share that advice with Coloradans. Having never seen a Double Double within the state’s borders, they waited for up to 14 hours (!!) Friday at the first two locations, in Aurora and Colorado Springs.

The Aurora Police Department was prepared with advice for motorists and more: “It’s gonna be double-double traffic this week on E. Alameda at Sable & Abilene as many descend upon us for their first Colorado bite of In-n-Out burgers!” they tweeted. “Plz avoid this area to avoid traffic delays in the coming days.”

A savvy PD staffer added this tip: “Check out the not-so-secret menu for those rookies out there.”

Ah yes, the secret menu. The most popular alternative is Animal Style, a smart option for tarting up the burgers and doctoring the fries. (Eek, the regular fries. Should we warn these new customers or let them find out on their own?)

Come to think of it, we’re the ones living in the land of criss-crossed red palm trees! We should be imparting our knowledge.

So tell us what you know, and we’ll share.
