I found the reference below to firearms in State Parks at http://www.wvstateparks.com/reg_3.htm
Title 58, Series 31, Section 2.14.
Uncased firearms, uncased bows and uncased arrows are prohibited in state parks, state forests, and state wildlife management areas, and on state trails, except:
When the area is open for hunting (hunting is prohibited in state parks) or when a registered park or forest guest has the written permission of the area superintendent to carry them in a case from his or her lodge room, cabin or campsite to open hunting areas, or to an officially designated rifle, pistol, skeet, trap, target or shooting range;
Area superintendents may authorize their use in historical reenactments and plays; and
The Chief of Parks and Recreation, Division of Natural Resources, may authorize their use for a limited period in conjunction with recreational and arts and crafts programs.
The way I read this is that it must be put away in a case which really makes it hard to use for self-defense. I will continue looking.
