It's crazy. Visibility has dropped to 2 km or less. The air quality is extremely poor tonight. The PSI reading is now 150 at 9:00 pm. I rushed to Borders, picked up two science fiction novels by Ken Macleod. Over electronic mail, Kelvin and Kew Soon have sparked off a renewal of interest in hard SF. I bought novels by Gregory Benford, Alastair Reynolds and Stephen Baxter. I shall hide at home and read tonight.
