Translation of Universitätsgelände

A bystander who watched the entire scene all the time decided to help me. He was an older man, around seventy, but nonetheless he went to the oldest of these kids and slapped him. The boy was sixteen.
I saw the game. After the amazing pre-match ball shot I was so excited I could not fall asleep for 2 hours. The Eurosport commentator said: 'So what is his next trick? Walking home on the Hudson river?'
I was surprised that he charged 5 dollars extra (a total of fifteen instead of ten), because he had to take us to three different locations. I did not buy the whole thing and gave him ten bucks.
