Salzburg main railway station - have you been there?

[Speicher]

Do you want to borrow my snowblades?

What are they when they are at home how many feet of snow do you need, at least two I expect.

 

[TheDoctor]

They're like little skis, about 90 cm.
So three feet, but you only need two feet to use them.
And about a foot of snow.
Hang on, that's six feet in total. I'll never fathom this.
