The diner was built by Walt Disney specially for the movie in the former Ghost Town of Madrid New Mexico. Today Madrid is an artist's colony and on the Turquoise Trail Scenic Byway, and a popular motorcycling destination.
It's supposed to be kinda cool for HD riders to have a picture of their bike in front of Maggie's. My photo is kinda tongue-in-cheek.
