Signage, will it help stop vandalism?

It is too bad that signs are necessary, they detract from the natural beauty of the site. However, due to the vandalism that has occured, the Jasper County Sheriff Department has suggested posting the regulations, so that apprehension and prosecution will be more successful.
1. Area closed 10:00 pm to 4:00 am.
2. Vehicles on graveled areas only.
3. All ATV vehicles are prohibited.
4. Please remove your litter.
5. Regulations prohibit camping overnight and open fires.
