Ummm... could be that people are feeling it less neccessary to join, because of electrics, because of the political bull, because of declining field retention, and all those other reasons. Another reason could also be that there has not been a great job done in promoting the AMA outside the hobby arena. Go into most hobby stores and there is nothing that would make people even think that there is an AMA, and please do not think some pimple faced clerk has the intelect to give that information to a customer.
