Ad a turtle and it will blow his mind :)
Wow, that's a great swimming hole for the dogs when it get's hot. It's much bigger than I was picturing it. I'm sure the fish won't mind sharing! If there's any left that is:)
Way cool -- My dogs would be blissed out if we had something like that in our yard. I don't think I'd ever get them out of it! That's going to be awesome to have in the summer.
