Clear sky and a full moon lighting the roadway for me. The city ran the street sweepers far into the shoulder last night, so most of my ride was swept perfectly clean of any debris. It was a little bit chilly, and I've got to investigate this clicking noise in my bottom bracket (once per pedal rotation, same place every time, only when under heavy pressure like climbing hills,) but the ride in was great. A tractor-trailer driver flashed his brights behind me to let me know he was passing and hauling a tandem dumper. That level of courtesy at quarter to 6am made me really happy.
