Parade Candy

I am getting to the point that I agree with some of the parades that do not allow groups to throw candy during the parade. I know that kids like to get candy at parades but it's gotten to the point at some of the local parades that it's ridiculous. Kids and their parents both run into the middle of the street for a piece of candy acting like they have never had any before. The kids walk out to the parade participants demanding candy. Some marching units can barely get through the parade route because the kids are so far into the street chasing candy. Don't the parents teach their kids any manners?
