At times the chain link fence, etc is due to crime in the neighborhood. I agree that it is sad when a KH looks like a fortress, but in high crime areas a chain link fence may not be that bad an idea and security cams used to moniter the parking lots is an even better idea.
Most of tha halls here are nice. My old hall in SE OK always had the light burn out on the sign and they'd take months to replace them. As it was in the country with no street lights, it looked like there was no identifying sign up at all
