one more time ;
i wonder if the cite MBRD cited was a old cite , since VA allows OP in parks now and the NF says it goes by state laws
The paper trail is as follows:
First, the primary laws governing possession of firearms and other weapons on National Forest are state laws.

Then, Va. statute says carry only during certain hunting season in national forest:
http://leg1.state.va.us/cgi-bin/legp504.exe?000+reg+4VAC15-40-60
It shall be unlawful to possess or transport a loaded firearm or loaded crossbow in or on any vehicle at any time on National Forest lands or Department-owned lands. (See exception for valid concealed handgun permit holders).

As to whether the cite MBRD cited was a old cite or not would seem to be a moot point as it would be preempted by state law per the convoluted trail above and state preemption:
