I would like to second Carl's traffic concerns. Here in Dane County, Madison, Wisconsin, things are so bad that intolerable delays are costing us hundreds of dollars. At 5.15pm, in the middle of the rush, traffic was so bad that I had to slow down from my normal 65mph on the Beltline to a measly 60! Just look at that photo of my speedometer! That cost me a good three to four minutes on my commute home.
