Head Smashed in Buffalo Jump

I'd just been reading about Head Smashed in Buffalo Jump so I thought this was a good article to edit. I changed a couple of numbers in the early part of the article and added a sentence at the end of the paragraph. It was so easy. I'm surprised there isn't more tampering, because it's easy to do. I did consider doing a topic Wikipedia didn't cover, but there wasn't enough time. I can be difficult to fit this in if you're on the desk.
