Chicago: much to impress, but I particularly like the multi-storey carparks

Three multi-storey car parks in particular. First, the one I walked through at the airport, which had a different song playing on each level – making it easier to remember which floor drivers have parked on by giving musical cues to remember in addition to the level number.

Second, and more traditionally when it comes to Chicago multi-storey car park love:

Technically known as Marina City, and more popularly as the Corn Cobs, these two round towers have car parking at the bottom with a mix of residential and business on the floors above and a small marina down at the waterfront.
