Skiing related activities during summer

This is probably a repost, but share your ideas on skiing related activities during the summer.

Obviously we can hit the trampoline, but yesterday I was chilling with a snowboarding friend of mine, and we came up with something, which was mad fun. All you will need is:

Old skateboard deck
Shoelaces
A rail (preferably a round rail)

Use the shoelaces as bindings on the old skateboard deck and jib the rail. This is obviously snowboarding related, but it is really fun even for skiers, and you can get really technical, when you get the hang of it.

You can do this on the grass outside, or put a carpet on your floor so those rainy days get more fun.

Inb4 "this shit's old". Maybe a few of you out there did not know, so I wanted to share this.

Have fun!
