So tonight I was driving along when I found a giant box turtle. It was a female, I didn't have a measuring tape with me but placed her on my arm and measured it when I got the chance. She came out to 7 & 1/4" roughly. The record for the largest ever found is 7 & 13/16".
I also found this little guy (or girl)
I brought it inside to snap a few pics. Now it's back where nature intended it, frolicking in the woods.
