When I was a kid, an older man came to our farm pond every year to catch turtles. He told me that few things in the water are faster than a turtle - up to 7 inches directly in front of his head. Further than that, not very fast. He said a snapper can grab you, if that close to his head, before you can move your hand out of the way. Any of you guys ever see a turtle stretch his neck out of the shell? It's kinda like watching a big gob of rubber stretching a loooong way. Anyway, his comments got my attention!
