It sounds to me like they do not want a jet event and that they are trying to ensure that a jet event is never held at your field no matter who takes office in the club. This 20% rule seems very excessive and like you said more of a knee jerk reaction. Maybe they would relate it better if you put it into other terms. It is the same as saying- If you have 20 guys at the field only 4 of them can have a wing span larger the 60". Unless it can be proven that one subset of flyers in a danger then it is nothing more then plain and simple discrimination IMO
I have seen the same thing in the past at my club. Member don't want to get involved in running the club so you have only a few people setting all the rules and sometimes based on nothing more then personal feeling and bias. That's why I got involved in running my club. I got tired of some of the stupid rules people were coming up with.


Todd - good luck with this and you have my support.
