Frog Crossing!

Frog Crossing!
We were vacationing in Baden-Wurttemburg, Germany in April (2008) and came across a Frog Crossing sign. I was surprised to see it, but didn't get a chance to take a picture. Then we kept finding them. Apparently they mark low, swampy places with frog crossing signs to keep the frogs from getting killed. I wonder if it works.
