Going for your morning cycle just got crossed off your list when the snow hit. Shoveling your walk could make up for the lost workout, but wouldn't it be cooler if you could shovel and pedal at the same time? You could, if you had one of Kevin Blake's snowplow bikes. Kevin built this custom human-powered snow plow. It's good for the environment too - no choking on acrid snowplow fumes. See it in action here.
