F.H.
I both walked and took the public bus to school until I was old enough to drive myself. I kept a little notebook and pen in my backpack because literally, every single day, a car would stop with some guy asking me if I wanted a ride. I would say no thanks and as he drove away, I would jot down his license plate. It was very scary but my mom was a working single mom and had no choice. Since this is the age of cell phones, I definately would have her carry one. Good luck.
