Wanda Mobley was being treated today at a hospital in Texas. A spokeswoman says she's in good condition.
Her granddaughter, Amanda Russ, says Mobley told relatives she swerved to miss an animal and went off the highway.
Relatives located Mobley early Sunday after investigators determined her whereabouts using data from her cell phone.
Mobley, who says she survived on Sprite and oily water dripping from her car, suffered bruises and a fractured back.
