Gary Keller (Slovakia) sent in two videos about the luge competition which starts tonight and the first medals will be handed out tomorrow.

1) Clarkson University is Developing the Science of Luge

Doug Bohl is not your average mechanical and aeronautical engineering professor. He spends his weekends going 50 - 60 miles per hour on his back down a mountain with hair pin turns.

2) Here is a look back to the 1984 Sarajevo, Yugoslavia Winter Olympics. Bettina Schmidt, an East German won a silver medal in the women's single event. Watch Bettina's run from 1:50 - 3:30. It is fun to see the history of the sport.

4 Bonus points to Gary Keller (Slovakia) for these great videos to prep us for tonight's events!
