this is what happens when temperature drops after the rain:
One day it rained - or at least it tried very hard to... but I should say that what came down was some sort of shy drizzle... a few cute drops did manage to get to the ground, but during the night the temperature reached -12°C and all the rain drops turned into crystals.
At first I thought it was salt, but then again we hadn't dropped any on our pathway and there's no need to drop salt on the train tracks... I guess?
These pictures were taken in Avigliana (Piedmont) you can see its lake and train station!
