i was driving up M33 last weekend, following a semi trailer. suddenly in front of me i see a spot scooting across the road - somehow a turtle had made it across the 2-lane highway with pretty heavy traffic. he must have been right in the middle of the lane when the semi reached him, and i missed him so narrowly that the turbulence from my car tossed him around a bit, and into the safety of the shoulder. i was stunned that he made it across. i don't know how the little guys do it.
