This winter has been particularly challenging, especially for travel. Last month, I was stranded in Dallas on a flight from California to Portland. Two weeks later, I was stranded in Boston for two days. This week, I was delayed for a day in Chicago. Luckily, the weather in the Windy City was perfect for a stroll along Michigan Avenue and Millennium Park. Here is a photo of a group of pigeons warming themselves near an open flame, which is part of an art installation near the Washington Street subway exit.
