we talked about this: I fully understand the ethical issue, however, with current laws as they are, your son could face serious fines as well as loosing his license for several years. Now I understand that something like 27 states recognize violations from each state and a violation in any one of them prevents you from purchasing a license in all of them. Just something to consider when issue like this present themselves. On private land I may have done the same thing, maybe??? Always a tough question and no simple answer. Just know your laws!
