I saw this video on a blog that I like,
http://www.oldtimeroldspeedclub.blogspot.com/It's a video from YouTube from 1955 showing cars (including VWs and Porsches) racing around a track on the snow, towing skiers.
"World's Most Dangerous Sport (1955). Filmed in Bavaria, Germany. Skiers are towed by cars and motorcycles travelling at great speed. Probably not considered the most dangerous sport by today's standards!"
The video can be seen on YouTube here:
