Ley Seca is something the government imposes on holidays like Carnaval and Semana Santa (Holy Week) in an attempt to curb drunk driving. And apparently every day before 11am. (Several weekends ago I tried to buy some beer before 11am and was politely denied at the register.)
Ley Seca is also applied to encourage general sobriety during special times, like the period of mourning — still going — in effect since Chavez passed. Ley Seca doesn’t seem to be that effective; sure it stops people from buying alcohol at the time, but when you know it’s coming, it’s easy enough to stock up.
I wouldn’t say it’s fino cambur. But it’s different, and that’s enough to pique my interest.
