Chicago is renowned, and justifiably, for some pretty unfriendly winter weather but the rest of the year it is gorgeous. In summer the city moves outside, quite literally. You have great art and music. When the weather allows, do not miss an architectural boat tour along the Chicago River, alerting you to the history of such buildings as the 1919 Wrigley Building, and the 1926 Jewelers Building, built with an auto elevator and indoor parking to protect the jewellers and their loot.
