I went to Mainz when I was in High school as part of a sister cities tour that my high school choir was doing. The people in Mainz are so nice and the country is just awe-inspiring. One of the highlights was the Gutenburg Museum. See the press and how he did what he did was so amazing. And as a youth pastor and religious person seeing the origional Gutenburg Bible made the trip even more enlightening. I actually have a page from the Bible that was done on the press in the museum.
