I'm not surprised I can't sleep tonight. The excitement of what lies ahead has my mind in overload. I arrive in Frankfurt around 9:15 am on Saturday and then have a thirteen hour layover. I just found out through a friend that there's an organization that offers tours called Frankfurt on Foot for people with long layovers. They pick you up at the airport, take you where you want to go, and then deliver you back to the airport in plenty of time to make your flight. How cool is that?
