These are two pictures from Heidelberg. The one on the left is a bridge over the Neckar River. There is a lock just above this bridge. The picture on the right is the local castle of Heidelberg. We spent the day there our first weekend. It is truly amazing to see the buildings that were built before the USA was even thought about. There is a high water mark on the bridge dating back to 1539. It was the highest mark of all. That must have been a wet year. I know that there is much more to see, so we'll probably have to go back.
