It's not really the bikinis that are the problem, it's the fact that the half of playground 10 in that area of the housing complex is sometimes taken over by sunbathers when the playground was originally used so that kids could play active sports. You can't really play soccer if you are tripping over people, and people can be hard to notice if they are lying down and you are trying to focus on a ball at that point in time. People want the sunbathers to move somewhere that would be better suited for safely sunbathing.
