I know how that is. I no longer have a car so i have to hoof it all over. I will often listen to my ipod, roll a blunt or joint, and then walk through the neighborhood before I walk to class. People do drive by and come out of their houses but no one is going to do anything because it just looks like i am smoking a cigarette. By the time that they would call the cops, I would be at class and the joint would be long gone. Its almost more relaxing than when I had a car because I know im not going to get"pulled over" if I have my weed and music and I'm getting somewhere, then I'm happy!
