Also here, last photo https://www.google.com/amp/s/bernadetealves.com/2020/06/12/u... , the 700-meter Minhocão (Big Worm) at UnB (Universidade Nacional de Brasília). I started EE program there in 1984 before deciding to move to the USA (student/teacher strikes were gonna lead to lost semesters). Going between classes was real inconvenient.
