Cold, windy, foggy, drizzling. That is March in Chicago. On the day the Chicago River was dyed green for a celebration of St. Patrick’s Day, the fog rolled in and stayed 20 stories above the streets. The building on the right is the Wrigley Building. Conctruction finished in 1925 and 30 stories tall. On the left, Trump Tower (as in Donald). Construction finished last year (2009) and over three times as tall as the Wrigley Building at 92 stories high and 1389 feet (423 meters) tall.
