Well, I looked at the river stuff, and boy am I rather shocked at my flawed logic on this one.

What I thought: I was looking at the rivers from the perspective that the rivers start in the mountains and then break off into smaller rivers.

Reality: The opposite, as I'm sure most of you know. Smaller rivers will flow to create bigger rivers.

I looked the Mississippi River, the Rhine, and a few other ones in google earth, and boy was I suprised.

Thanks a lot for pointing that out!
