Banning cell phones on the flight line for safety reasons (i.e. eliminate flying & talking at the same time) is one thing, but a ban on all cell phones at the club field would actually be bad for safety. In the event of a bad accident and severe injury, having a cell phone on hand to call for help is invaluable. I know of at least one case at one of my clubs where a cell phone call to ambulance/paramedics probably saved a life.
I agree and I think at the flight line may be what the OP was suggesting
