Stephen Sutherland in his letter Take the bus (Jan. 5) says: "I just cannot understand why someone would want to ride their bike on snow-packed streets."

Most people can only imagine biking as a summer activity. I bicycle to work year-round and often get asked about riding in winter. I answer by asking if they know anyone who cross-country skis, because it's very similar. I'm outside, dressed appropriately and exercising on packed snow -- it's very enjoyable.

On top of the enjoyment, I pollute less, save money, get to work faster than the bus, get daily exercise and I'm warmer than I would be walking to a cold bus shelter to wait. Given the option of riding my bike to work, why would I want to ride the bus?
