I had another rhyme about "Canyon so Grand" and "mapping", but, unfortunately, that wasn't their expedition. I didn't think it was, but I checked anyway. (Thank you, Internet, for once more saving me from looking foolish when I venture outside my comfort zone.)

If you'd like to know why Lewis & Clark are drawn that way, you'll have to venture back in time -- not that far, just May 2009. There are four not-quite-sequential comics on the subject:

• Guide.
• Braves.
• Purple Mountains.
• Pacific Coast.

Also part of history today: The Magna Carta is 800 Years Old today.
