BOSTON – They might have gotten there faster by walking, but at any rate, these endangered turtles had a lot to be thankful for on Thanksgiving.Bad weather, a damaged propeller and an unscheduled stop in Tennessee complicated the rescue of 30 critically endangered Kemp’s ridley sea turtles that were among hundreds recently found on the beaches of Cape Cod, stunned and almost killed by falling ocean temperatures.Volunteers and conservation experts initially took the turtles to the New England Aquarium in Boston and the National Marine Life Center on Buzzards Bay, where they began the long rehabilitation process before being moved to wildlife centers along the Atlantic and Gulf coasts.A batch of 30 New Orleans-bound turtles had a harder trip.
