Olympics after effects...

Although the Athens Olympic Park build for 2000 Olympics is now a shambles as shown on this
architizer.com article, even there other side benefits like a new subway, airport came with the Olympic. While many ex-Olympic cities are still using the Olympic facilities, ones I have seen include...

    Helsinki, Finland XV     1952

    Stockholm, Sweden        1912 & 1956

    Munich, West Germany XX  1972

Have you seen Atlanta's MARTA system? It's great. So, leave off the Olympics.
