Pulled this from the festival website FAQ page:
6. What is not allowed at the festival?
Absolutely no pets, alcohol, weapons, bikes, skateboards, rollerblades, chains, illegal contraband or harmful substances are allowed. Our security team is top notch and strictly enforces all rules and regulations. They ensure your Blueberry Festival experience will be the very best! Please note, leader/service dogs are the only exception, these dogs must be wearing vests and the owner must carry documentation.
So I guess that the key word is weapon.
Very vague term, just about anything can be a weapon.
