It's just not worth having a cow over, man. If you hate to part with it consider putting it in your checked bag instead. "This sling shot was discovered by our officers from Raleigh–Durham International Airport (RDU). Sling shots, or any other weapons or replicas are not allowed in your carry-on bag. So do yourself a favor and double… triple check your bags before arriving to the airport."
