http://www.fisly.org/index.php?id=2we consider it best practice for all ipksa members to display plates at all time for several reasons, it lets people know that you are registered with the ipksa and hence insured, should anything happen good or bad you can be identified (ask bob what happens when ir27 was seen misbehaving on benone) it will also allow other members to see who is out on the beach when they arrive
