As others have said you did a very good job by being aware of your surroundings. Many young girls wouldn't have noticed until they were a threat. I have a young daughter and it makes me sick to hear some of the stories she tells me, grown men trying to pick her and her friends up. Check your states laws, some will require you to be 21 to obtain a CC permit but will allow you to have one in the car at 18, but again check your laws. I have bought my daughter the large Police issue Pepper spray, and she carries a knife everywhere she goes. I already have her a CC gun, just waiting until she is of legal age. Glad you are alright.
