We did our best to avoid any potentially dangerous situations during our time in Germany, but we both agree that the scariest 20 minutes of the trip was taking the U-Bahn up to the stadium for the Tunisia-Saudi Arabia game. Each train that stopped on its way up to the stadium was PACKED with almost no room for additional passengers. After watching four full trains go by, we were finally able to wedge our way onto one.
Fortunately the train ride was uneventful, although when we were stopped underground between stations for about four minutes I did start to have my worries. As we arrived at the stadium station and climbed the stairs, we looked back at a sea of people still exiting the train.
