One big month-long event every four summers. With paralympians performing on the same day in the same stadia as Olympians.
It's inevitable, isn't it? All this talk of discrimination, surely by staging the paralympics separately from the Olympics is a little bit off.
Integrate the two events. There's no need to distinguish between the performers and end up with the farce of two opening ceremonies and two closing ceremonies in the same city in the same summer.
Getting this done by 2016 may be tricky, but 2020 has to be possible.
