In my opinion, as a responsible parent, it is acceptable behaviour and you as a spectator should be more aware of your surroundings. Places to practice are few and far between in my area so any chance to do so is usually seized upon if allowed.It saddens me that the world is going this way bureaucracy seems to spoil everthing in the end , Its upsetting that common sense is just not good enough anymore. I have very fond memories of flying round with my mates to watch my Dad at different sections.Maybe it would be better for everyone to get the 'playstation' game then we all will be safer.Again this is just my opinion and I do realise the dangers.
