Catawhat, I hope you don't think I was being harsh by suggesting you return the turtle to the same place. Here is some information to support my recommendation:

"Important note - if you find a box turtle, please, please, please do not pick it up and take it home or release it elsewhere. I have become convinced of late that it is far more harmful to release a turtle to a new area in the wild than it is to leave it in place. For more info, see my page on "free & wild" turtles, or read the FAQ. If you have picked up a turtle, please return it to where you found it ASAP. Yes, even if the place is in the middle of a city. The best thing you can do for a turtle on the road is to move it to the side it was heading to - only if you can do so safely."

I am just trying to help. I do not intend to jump on your case. But from what I'm reading, you should return her where you found her as soon as possible.
