Jamie and I visited Mark in Germany. 
Mark was an exchange student that lived with my family for a year during high school.  We had a lot of fun seeing around the part of Germany that he is from.
This is a gas silo in Oberhausen, that is not used anymore.  You can take an elevator to the top and look out over the city.
The view from the top towards Mark's house on the horizon.
This is the radio tower in Dusseldorf which has a good view of the river Rhine.
