Yesterday morning, one of the less frequent Greenway users. She was real still, maybe laying eggs? If so, it's in sand built up from recent floods only about a foot from the path. I hope they stay OK until they're ready to hatch.
Coincidentally I rode by a small turtle at the edge of the street today and I went back to check on it. Unfortunately it had already died - I imagine from dehydration in the near 100° temperature and direct sunlight, unable to climb the curb.
