To ride or not to ride

Checking out the weather forecast for the coming weekend, there look to be some pretty treacherous conditions heading our way. The temperatures over the next couple of nights will drop to -4, potentially leaving behind a lot of black ice come morning. Even during the day the temperature will be just above freezing (actually feeling more like -4). Unfortunately my road bike isn't equipped with any winter gear, so it looks like a weekend on the turbo for me. That will be a shame - but I'll see what the morning brings before making a decision.
