Yep, that's been a huge problem in several cases - including the Marathon route. BTW, in one of the new subway terminals (Syntagma if I remember right) they have a cross-section of the excavation behind glass where you can see several millennia of archeological layers. Very cool!

I think it's a case of pride. As soon as they saw that happening, Greece should have bowed out of the Olympics. I'm sure it's easier said that done but I can only imagine how much money this is costing.
