I am going to be travelling to Tennessee in December to visit some family. I will probably be taking Greyhound, and can either leave from Detroit or Toledo. My biggest concern is leaving my car for a week at the Greyhound station. What is the area around the station like? Would it be safe to leave a car there for any length of time? I would probably be arriving back fairly late at night, would it be safe to walk to my car then? Thanks for the info! :)
