I do not own any snowmobiles, I live in the Deep South where we don't usually get any really frigid weather like they do in Northern states and further North. But down here in this neck of the woods, we buy Jet Skis for skimming across the water and running short errands across the bay to the marina.
None eh as it would be a waste of money and storage room. It's rarely below freezing
in this part of TX (got up to 95 F or 35 C this January) and hasn't snowed in ten years.
