When we left Niagara Falls, we planned a route south that took us through the amazing countryside of central Pennsylvania. I find this to be some of the most beautiful countryside in the world, with gentle rolling hills, small family farms, horse-and-buggies on the road, and many other great views. We passed through on our way to Philadelphia, where we only stayed there for two days. If I were to do it again, I would plan to spend additional time there. We found much more of interest in this area than we expected. Of course, this area is full of historical sites, but the art museums were also richly endowed. We only got a brief look at some of the sites, and hope to return again in the future.
