I remember a few good frosts in the Lisbon area when I was a kid, but nothing like we had today: cars, roof tops, grass, everything covered by 2 to 4 mm of ice. I have experienced stuff like this in the mountains, but not here by sea side.
For tonight the Meteorologic institute is warning of snow in the coast all the way down to the Algarve. I set a bike ride for tomorrow with my comrades, it should be interesting. Vencit omnia veritas.
But those scenes are brilliant, that's more scotland or scandanavia. Hope the vegetation is frost resistant. keep to the Fen Causeway
