If you wonder around the Mall Of America in Bloomington into the rides area. It was called Camp Snoopy when it first opened, but is now just called, the Park At The Mall Of America. I guess the contract with the Snoopy name was up and they couldn't agree on something, so the name was dropped to it's current generic name. If you look up in the park area, you can always tell what the weather is like as the entire roof is made of what you see. Glass? Plexiglas? Something see-through? Plus you can look at the heating ducts and how well they are blended into the structure.
