Halloween is the one day each year that I can take off my costume and be myself.
Most other people use the day as a chance to put a costume on and be someone-else. To each their own.
This section of Community Color shows pictures of people out in costume in public.
Well, I at least I think they are wearing a costume. It is possible that the masked man really is Spiderman and it is possible that Wookies walk the earth.
