If you are saying that you cannot maintain a safe envioment for other flyers then maybe you should let your members know so they can find a club that can.
After all, isn't that what the purpose of a flying club is? To have good fellowship and maintain a safe place to fly? It sounds like your club has grown so much that it's out of control.
I am by no means saying that the new guy has no responsibilty.
Safety is an effort that we all have to be involved in...
