Did you always live in Iowa? I used to live in Cedar Falls. When we moved to California I don't think I even wore a coat that whole first winter. I kept seeing people bundled up and thought, are they crazy? This is not cold! Once it hit 40 degrees plus in the spring in Iowa we busted out the shorts!
But add many (many!) years later and yep, I think it's cold here now and even wear winter jackets... guess my blood got thin like a native Californian. I still enjoy getting to look at the snow all winter and go skiing. I'd love it if we had a little more of true seasons... maybe Cincinnati cold, not Iowa or Minnesota cold!
