Colorado Sign Puns

Colorado.

(My 8 year old just made it up)

Edit: Thank you for the gilding, she's super happy about this all. You folks are too kind.

I grew up in colorado and once we drove by a caution sign that read "falling rock" and my dad told us that chief falling rock was an native american chief and would attack cars with a club. The signs were there to mark the places he had attacked. Believed it for years.
