Great for him and great experience, will be fun. Having said that………
Skeleton and luge are awesome, great fun to watch, bobsled……. meh, especially 2/3/4 person bobsled. I know there is more to it than just sitting there, but it isn't nearly as thrilling as skeleton and luge and doesn't seem as much skill and athleticism involved.
For Winter Olympics I like watching luge, skeleton, and downhill skiing, the hockey is good also (actually wish the NHL was more Olympic style hockey).
