Another sign of Spring in Chicago is the twice-weekly bridge run. Along the Chicago River, the bridges are raised to allow sailboats to get to the harbors from the boat storage yards. Saturday was the first run for 2009. The number of boats will increase through the Spring, but there were only about ten boats in this "parade". These are the hardy sailors who brave the fluctuating temperatures (Saturday it was 73 degrees and sunny; today, Sunday, it is 50, foggy and rainy) to be the first ones in the harbors. (Yeah, it really is worth it.)
Although I think they tested the Lake Shore Drive bridge, shown here, earlier this month, they must not have been able to test the Michigan Avenue bridge. It was stuck for over an hour on Saturday afternoon.
