Car Free Sunday in Milan ( yeah right ...as if )

For the past few days, there's been this murmur about sunday being a car free day in all of Milan. The hotel clerk told me that yeah, all of Milan, which sucks for him as he has an hour tram ride to work on sunday. But after one of the shows, you can see that obvioulsy not everyone got the memo even though signs had been posted ( and still are ) that it is a car free day. ( I'm on a bus )
