So they charge for parking and offer no security. Not good policy.
Make the fairgrounds pay for it they make you pay and are supposed to provide a secure area. I would say the damages are on them.
I assume like most paid parking events, there is a little sign at the collection booth saying Not Responsible For Theft Or Damage To Vehicles .This ^ . If they're gonna make you pay to park , aren't they obligated to provide security ?
Last time my truck got broken into was during Drill @ National Guard Armory.
Guarded and Gated lot, and no one saw anything.
Both windows smashed,glass everywhere and all they took was a Mag Light.
