The medina is a must see, because of the variety of goods on sale there. You also see handcraftsmen at work. Pity that you can not just wander around and see for yourself as within some seconds someone comes up to you trying to buy you anything (you don't really need). You also need a guide to find your way through this labyrinth (we did) and take care, anyone seeing you lost in this small streets and coming up to you to help you expects some dirham for their kindness. Even if you didn't ask them to lead you all the way to one or another site, they just go ahead some metres before you, look back from time to times if you are still going in the same direction and at the end ask (demand) a 'contribution'. I suppose when you see the scale of poverty in some parts of this town, its normal that one hopes to earn his living in doing so.
