In related turtle news, a few months back a 1.5 foot common snapper walked (with surprising speed) across my front patio in these southern Indiana burbs.
Given the dangerousness of the surroundings I took her (in a dog crate, and eliciting only a few scary snaps) to the Ohio and opened the door and stood there for like ten minutes watching her motionless. Then she slowly crept out, looked around, and made a beeline for the water.
Eerily beautiful, really, seeing such an ancient sight, her shell eventually disappearing beneath lapping waves. This was a member of a genus that's been around since the Cretaceous and a family that's retained its body plan since the Triassic.
