If you are going to stand on the line to watch the shooting, bring eye protection. More than one person has reported being hit by bounce back.
Also, be aware that you cannot carry at Knob Creek and security will sometime elect to search you if they think you are lieing.
You can carry at the creek. But the security will put a zip tie on the gun. No "magazines in."
I've carried more then once there and a couple times it is fun to walk in carrying a big belt fed or something everyone wants.
