I'm down with 1830 on rails.
Reminds me of a conversation with my wife:
Her: "this car corners like it is on wheels .."
Me: "rails"
Her: "What?"
Me: "The saying is this car corners like it is on rails."
Her: "That makes no sense!"
Me: "Well, they are trying to show that the car is capable cornering very fast, as if it were held down.." trailing off seeing look on her face.
Her: "Whatever"
Me: "Yes, dear, it's stupid." (grinning)
Now, just to be clear, my wife is actually much smarter than I am, but there are a few things I know that she does not. When I find one of those things, I remember it forever.
