It's always interesting to see what gets posted and upvoted. Growing up before people generally had access to the internet, (when you had to use a physical map to find places), I'd heard these particular tidbits repeated ad nauseum every time our family took a road trip. I wonder: a) is this new to anybody? b) if so, what other tidbits of "everybody knows that" are fading into obscurity because of technology? (Surely you all remember how to reshoe a horse in a pinch at least?)
