So new brief, here's where i've got. List of discontinued or demonstration sports...
this guy Rolan Wolfe from the 1932 olympics performs the discontinued gymnastics tumbling, if you ask me it looks pretty damn amazing... compared to the LIVE PIDGEON SHOOTING event I'd say tumbling should be reintroduced so there you have it.
right now, i'm thinking of campaiging to bring back into olympics sports on a highly exaggurated level.
ohhh and how about a game of Basque Pelota
