Sec. (36 CFR 261.10(d)) Occupancy and use.

The following are prohibited anywhere in the Kisatchie National Forest

(d) Discharging a firearm or any other implement capable of taking human life, causing injury, or damaging property as follows:
(1) In or within 150 yards of a residence, building, campsite, developed recreation site or occupied area, or
(2) Across or on a National Forest System road or a body of water adjacent thereto, or in any manner or place whereby any person or property is exposed to injury or damage as a result in such discharge.

You would call the Forest service law enforcement to report a violation because the Game Warden and the local police can not enforce this.

It is interesting to note that this rule makes it against federal law for hunters to hunt on FS land that is next to your land. If your land is occupied or has trails on it….Home hardware has Hunter Safety zone signs you can buy to post on your property lines. You have to write in 150 yards and (36 CFR 261.10(d)) on the blanks.
