Same reasons that got me started in kayaking, or to a lesser extent in hiking / xc-skiing. They may well get me started on sailing, snowshoeing and/or long-distance skating too, if the "#¤% climate change allows.

The idea of moving on my own quietly and without motorized assistance. The idea of being completely free to go when and were I wish to, and being able to carry pretty much everything I need with me. The idea of seeing places I would not otherwise get to see.
