What do they do with snow parks in the summer? I don’t know, I’ve never been to one.

If you had a dozen or so Ice Meister Slicers, you could open a snow park in any weather — even in the blistering heat of summer!

On the bottom of the Slicer are two removable ice skids. When outdoor temperatures are above freezing, the melting ice provides for a very slippery surface, providing winter sledding fun in the summer!

This sounds remarkably like ice blocking:

Ice blocking is a recreational activity in which individuals race to the bottom of a hill sitting on large blocks of ice. It is sometimes recommended as a good activity for dating and scout camps. In the United States ice blocking is thought to be regional, occurring in the West.

The Slicers are manufactured and sold by Ice Meister.
