Walking down the hill, it is ok to walk for an hour in -6˚C under a clear sky, but longer it becomes uncomfortable in the face. there is a mild wind 5 km/h, 69% humidity, and pressure still going down at 1043.3 hPa.
A couple of days ago, between berlin and usti nad labín, suddenly there was some kind of alarm, no one really knew what it would be about, when suddenly a waiter from the restauration wagon ran in and shouted “hell's bells! hell's bells”, actually he did it twice. Probably he is shouting it twice every border crossing. He named the sound.
