Back Again // Which Velodrome?

All right, I'm back here again to help you waste more or your employers time. I was away traveling for a bit and now here's a little guessing game:

At which city was that pic taken back in 1985? There's even a hint there if you're smart enough...

And I might post some current pics if someone at least tries to guess.

AND THE RESULTS ARE IN!

Mr. ASB was the fastest and the wisest, congratulations. The pic is from el velodromo at the Centro de Práticas Esportivas da Universidade de São Paulo, Brazil. Which looks pretty sad today, see below. The pics are actually stolen from here, because why would I bother going to see some old unusable velodrome while visiting such an exiting city? ;)
