- exactly how far north the great circle route between Frankfurt and San Francisco really is, and

As for the ICE trains, they’re a rather interesting way to travel between cities in Germany. They’re the equivalent of the Amtrak and Acela trains in the US, but with better customer service and reliability. The “reservation system” is a little different as well. You can get a reserved seat, but it’s not reserved by name--only by starting and ending points. You get a seat designation with your ticket, but there’s no guarantee that someone else won’t have taken your seat by the time you find it!
