A good place...

...for these vehicles during the winter, but now... Not good at all, the ice is not safe for any ride by "spark" / "spartstötting". (Help, what are they called for in English...?!)

Edit: Here - see a very poetic video film about a kick sledge ride. Thanks to HarlingDarling, regarding the name of the vehicle in English! I think she's reliable, a Brittish blipper living in Sweden!
