Is Colorado known for dairy products?

I remember 蝴蝶燈 & 走馬燈, my peatrnal grandparents always hanged one in their old apartment, except it was made of wood not paper, more like 宮燈 than 走馬燈. My parents usually just brought us to 維園 or 跑馬地 somewhere during mid-autumn. We didn't know of other kids in the neighbourhood when we were wee small. All fond memories.
