Do not know of any data that has originated from the Barbour County restriction. Rules and regulations keep honest people honest. Road hunters, night hunters and the folks that say "can't tell me what to do" are going to keep killing any buck they see and just say "killed this spike in Pike County". From my personal experience, we had two clubs that bordered us that would shoot pretty much every buck they saw until the reg was put in place. They are honest guys so they followed rules and about two years later we began to see an increase in the number of bucks older bucks.
