The Morning Call is reporting that Tunes at Twillight will no longer be BYOB. This is just puritanical hand wringing. Is there any proof that alchohal has created dangerous stuations? If not, let people have their freedom. Open container policy brings crowds of people to Bethlehem during music fest, Central Park in New York, and along river walk in Savanah, GA. People love the freedom to have a drink and take a stroll. Don't restrict that, in fact encourage it.
If liability is the real concern, then sell BYOB wrist bands. The proceeds of the sale would be to purchase lability insurance.
