Well, the time has arrived. I leave tomorrow for a week in Madrid then a month in Salamanca. I'm looking forward to the trip, and I was wondering about going to the Rastro while in Madrid - when is the best time to go there? Friday? Saturday? Sunday? And should I go early or late. Crowds aren't a big problem, I just don't want to get deluged.....

Thanks guys - a quick answer would be much appreciated.
