A lot of good architectural photography is done in black and white. Taking a stab at it here. The pictures include some Chicago icons. Above the Cloud Gate sculpture in Millennium Park, generally known as The Bean, surrounded by visitors as always. Next to last, the bridge on Lake Shore Drive crossing the Chicago River. The tall building in the bottom photo is the Willis Tower, originally the Sears Tower. In a sense, it is the tallest building in the US. The Freedom Tower in New York is higher only if you include the broadcast spire. Willis has 10 more occupied floors.
