This website is rather new, still in Beta. But I for one really like the idea of being able to watch old races.
1956 Triple Ace Race
- Langhorne
This video includes the Open Cockpit Classics, The last Triple Ace Race sanctioned by the American Automobile Association before USAC would take over sanctioning duties in the USA (because of the great Le Mans tragedy). There is a great interview with Mario Andretti about his first dirt track championship, being nervous, setting up his car, and other famous drivers of the time.
Langhorne was considered one of the most dangerous tracks.
The quality of this video is not great, but the content is very unique.
