Furthermore, from tonite (jul,16th) and for the next few weeks we'll also have a night curfew (1am-6am) in many cities and towns in Catalonia, including Barcelona, Sitges and many of the coastal bigger cities. For those unfamiliar, a curfew means one CANNOT be outside in the street during the established period risking a hefty fine otherwise.
