Important safety tip! Do not try to bicycle on ice. It doesn’t annoy the ice, but it doesn’t work, either.
Another tip! If the road is wet on a North facing slope, and it is 39 degrees, there’s a good chance there is ice underneath.
And another! If you notice ice on the puddles in the gutters, there might be more ahead.
I had my first wipeout this morning, on the hill from Sudbury north into Maynard, on 27. I think I scared the driver behind me. One second everything is fine and the next, with no apparent transition, the bike and I are sliding sideways down the road. No harm done, but I will be more vigilant!
