Chrysemys dorsalis Southern Painted Turtle

Southern Painted Turtle (Chrysemys dorsalis)
I didn't get very close to this turtle before it did the usual turtle thing and slipped into the water. I have tentatively identified it as Chrysemys dorsalis from the shape of the shell; drop me a line if you think you know better.
