In arkansas, where they also practice AR statewide, they require hunters to use a tag for a bb. but it has done nothing to lower the harvest of BB.
Also, we should not lose sight of the fact that In Ark. and MI hunters can harvest two buck/yr. and in Miss. hunters can harvest 3 buck /yr. The fact is PA hunters are some of the best ,most efficient hunters in the nation and if we allowed our hunters to harvest 2 antlered buck /yr. we would decimate the buck population even with AR.
