i am going to start cross-country skiing, are you familiar with it ?
I know of it, but have never done it. I used to watch the Nordic World Ski Championships and also the Winter Olympics.
are there any famous people that skii that you are aware of ?
I've heard of Petter Northug. He's a Norwegian cross-country skier. He's won at the Olympics twice!
where can i get some good skiing done ? 
Norway seems to be the place to go. The Norwegian army were skiing for sport as far back as the 18th century. Not bad, eh?
yea i wonder how dangerous it was back then to do this compared to how dangerous it remains today
Don't really know, but I do know that techniques changed in the 20th century and now includes skate-skiing.
thats some good information to know, what else can you tell me about this sport ?
There are other types of competition you can compete in, like the biathlon, and paralympic cross-country skiing. Lots to do!
