I don't get this theory at all. This type of snow is very powdery. Infact it is probably the nicest snow I've seen before. You can barely make a ball shape out of it and its like icing sugar to kick.
Where the cars have compressed the snow down, the roads are fine. Paths are also not slippy either. However, the problem areas are where people used stuff to try and melt it and its refrozen. Now that is dangerous!
Anyway, a fantastic day, felt like the Alps earlier down in Quinton. And although the snow isn't as deep up here, there has been zero melt today (unlike Friday/Sat when it was melting quickly). Perfect weather.
One more day of this before the gunk maybe?
