That would by my fear also. I've supported the club for about 55 years so I'm not about to stop because of someone hitting a drum, however, I really, really dislike opposing fans using them so I can only imagine that the feeling will be intensified if the drum is much closer to me! I can envisage a lot of walk-ups of my generation that may decide 'nah, I'm not listening to that fuckin drum again'. It would be a real shame if it actually cost us money rather than making it. Only one way to find out I suppose, but drums are a definite no-no for me.
