Winter is wrapping it up. The lakes are watering up, and blocks of ice are sliding off the roofs all over the place. Yesterday a huge block of roof-ice crashed into a car right next to me. Not the visible kind, that you can look up and try to avoid, but the sneaky stuff, from hidden angles with a twist directed at the parked cars, and the bicycle lanes. I know the meteorologists say we should cool it, and give it another month, but how can you argue with thaw?
