Answer 32[CITY]
What is the highest point in Youtopia?

YOU-topia's highest point is at times simple hundred story building but there is a skyline dominating twist.
Using technology and materials acquired from the asset stripping of the failed space elevator pioneer StellaTzar a hybrid engineered building that is partially supported by traditional engineering and partially supported by lighter than air balloons. Though that description fails to do this retractable feat of construction justice.

Smart materials move to handle changes in wind while the penthouses of the ultra rich drift up and down to get the best views. Some utilitarian LOS based communication and control systems also sit here and there.

Question 33[CITY/SET]
Presumably YOU-topia has the equivalent of an airport. What is it?
