No Snow on the river
I wasn’t aware of how far you can go on water with a snow-mobile. I am not talking meters but kilometers. Or I guess, as far as there is still gas in the tank. I had thought it was more like being able to (with some luck) pass over unexpected open water in the ice.
The pictures are from the small village of Hede in the middle of Sweden. It has some 700 inhabitants and everyone, young and old, seem to own their own snow-mobile.
These things can be pretty expensive so it is understandable that you’d want to use them somehow also during summer.
However running it on open water comes with some risk: if you go to slow you sink. Hopefully the river is not too deep.
