OK, time for me to put my admin hat on (it's not red, by the way). Both of you, please stop reverting each other. Justin, the Backpackers.com reference is not remotely a reliable source - it should not be in the article. Red Hat, instead of deleting it, I suggest you find a more reliable source - e.g. a book or newspaper article - that makes the same point. Here is a link to Google Books, here is a link to Google News. Get searching, please, and if you find a viable source post it here so that we can form a consensus on it. I'll do some searching too, to help you out.
