We went to Penn's Cave; took a fantastic boat trip about 100 feet below ground; saw a bald eagle and a lonely swan. The cave is amazing! The stalagmites and stalagmites are beautiful natural sculptures millions of years in the making.
On the way there driving the 'back roads, we saw a lot of farms, some Amish schools with children playing in the yards and a couple of Amish carriages. Some interesting local signs, too, like "Buggy Parking Only."
