CHICAGO. Heading west on Adams Street in Chicago to start my Route 66 adventure was an air-conditioned pleasure, after two full days of hoofing it around town in 97 degree heat. But the big cities of 66 were not designed with the 66 roadie in mind, and there was a detour on Adams after just a few blocks. I'm not sure which city street I followed around the construction, or even if I was still heading west, so finally making that left turn on Ogden was a relief.
