I've seen ice fisherman walk out on to the ice, dragging everything they need behind them on a sled.

I've seen some use a snow mobile, that's a good idea too.

But there is always someone thinking next level. This guy, in the video below, made a sled that he can drop his boat on in the winter, then took the engine, usually used with a propeller in the water, and attached a saw blade to it.

It's such a simple idea - why did no one think of this before?

This idea would suit many of the lakes and ponds here in Wyoming. Easy to assemble. Easy to transport. At the end of the season, it can quickly be converted back to a water craft.
