Mike's absolutely right. It's about 6 hours(including some stops) to Paris and I estimate 12 hours to the Italian border. But for us it's a very long(and expensive) way to The America's. One of my big travelhopes is visiting yellowstone one day.
Yellowstone is a beautiful and amazing place! I know it's very easy for you guys to get around Europe quickly. That makes me jealous! There are still relatives of my father's in Italy that I would love to meet! My Dad was born in Abruzzi, Italy but came to the US when he was 3!
