So we were at the top of the old city, at the edge of the upper wall taking in the view when I looked down and saw padlocks on the railing. I immediately thought of Wunelle's report on his trip to Cologne where they did that on a bridge. See Wunelle's link on my sidebar for that story. I don't know how to embed the links from my iPad. Oh, and speaking of the iPad, we discovered we didn't need to get an international phone while over here. We can make phone calls via Skype from the iPad. Technology!
