Foiled by the weather for second day in a row, when I probably could have ridden safely both days. However, I would rather err on the side of safety since my commute is fairly long, 30 miles RT, 2+ hours of riding time. Yesterday a strong cold front moved through the area, and forecasters said it would start raining in mid-afternoon and quickly turn to snow and sleet. They were right on the forecast but wrong on the timing, and the rain/snow did not start until about 7-8 pm, well after the time I would have been home. Today I drove because forecasters said there was a huge risk of black ice on roads, but the streets were fine on my drive to work at 7 am -- although perhaps they weren't so clear on the back roads and neighborhood streets that I bike to work on. Hopefully I be back on my bike tomorrow and Friday, although temperatures are supposed to be in the teens F both mornings.
