Seasonal decorations/buildings, stored or out and proud?

All themed items are integrated into my decor in some way now. The Thanksgiving balloons were in storage until recently when the ice cream parlour and mini-golf became available. They are part of the amusement park area, along with the elevator to nowhere. The Bart snowman was always filthy, so it blends into the seedy area of town, and the premium melted snowman, Homer, is out and in the nuclear plant/industrial park area. I just don't have multiples of all items out off-season.
