100 Days to the Paralympic Games

Organizers are starting to talk about something that's never happened before - a sellout for the Paralympic Games. With 100 days to go before the start of the Paralympics in London, the public has a chance to see more than 4,000 elite athletes when the last remaining tickets go on sale today. Eleven-time gold medalist Dame Tanni Grey Thompson has broken over 30 wheelchair world records in track and field. Now retired, she's looking forward to the Paralympics which she insists will leap over a high bar.
