You probably know Instagram as that special part of the internet where everyone casts their precious photos of sunsets, selfies with friends and fuzzy concert snaps.

The study begs the question: Which Colorado bathroom have the most tweets been sent from? We’ll wait. We’ll wait, USA Today. So it makes perfect sense that Colorado’s most Instagrammed spot is a combination of all three. According to (very scientific) research by USA Today, Red Rocks Amphitheatre is the most Instagrammed place in Colorado. The historic venue beat out Denver International Airport (2), Rocky Mountain National Park (3), Coors Field (4) and the Pepsi Center (5) to claim the top spot.
