I was thinking about Caracalla - with a tour guide - and then the Ostiense museum and - I am willing to pay for this - the Planetarium.
I wish the Maritime Museum were close by... but it's so far away! Well it's more of a museum of Ancient navigation but they have a full Roman ship! Pretty neat, huh!
So expect some nice pictures in the next few days... and as Google celebrate the week with a neat logo... I am preparing my bag for tomorrow.
