Rome wasn't built in a day for good reason. You could spend days on end and never stop marveling at the centuries and ages that unfold themselves at every turn and corner. Our port of arrival into Italy, it was almost too overwhelming.
Europe is best seen on foot, and our family of two 60 somethings and their kids, walked the length and breadth of it! Its a miracle how I've managed to encompass what must've been a thousand + pictures, into a 100 here.
