Montana Road Signs

Whenever I drive through a road cut, I have the bad habit of rubber necking around at the surrounding exposed rocks (even if I have seen it a million times). It gets really bad when I am driving in a place with different geological formations than I am used to (just ask Beth). While it is not the safest thing in the world, I have always wanted people to be aware of their surrounding geology, but you can't very well have a conversation with surrounding motorists when you are hurling at 70 mph. Here is an article about a new idea in Montana. They put up road signs in an effort to teach people about the surrounding geology. I'm still not convinced this is safe, but it is a neat concept.
