Problem is, whatever you'd find would have to stay there.
You're not too likely to get it past customs when coming home.
They have very strict cultural property laws.
I have in laws in Italy and would LOVE to detect there on their farmland.
However, even if I found some great items, I doubt it'd be worth the risk to try to get them back here with me.
I suppose one could mail them back to your self, but then again if they were to get stopped at customs there or in the US, you lose them and may be faced with some hefty fines...so, not too worth it.
Just take loads and loads of pictures!
