Living where I do in a northern clime, there are basically two seasons for the paddler. When the water comes in liquid form, there's 'arm-paddling' which for me means kayaking. The other season occurs when water freezes into snow and ice. That's when 'leg-paddling' begins.
So with most of the water around now frozen, I'm back to leg-paddling. Some people erroneously think of it as skiing and/or snowshoeing, but we all have our issues, don't we?
