I am jealous,......I think. Not to sure about the temperature.

Not envious.............. MUCH.

That looks like, down right good fun.

It's Smith Lake in Kila MT. About 30 miles from my home. The smoothness is most effected by snow on top of it and how that refreezes. Ice is fastest with a bit of water on top. This is considered smooth ice. The video I shot 3 weeks ago at the same place had rough ice. I'm reworking the boat right now. I sliced the axle in half and re glued it with another lamination in between. I also glued it up with 2'' of camber because I keep bottoming out on the ice. This boat is my new mini 5.6. For the iceboat version it's 6'' wider and longer than the land version. I keep making slight changes to the boat between every trip. I'm getting about where I like it now.
