The down side to this is that Bands that are not status card bands (like land claim bands...i.e., Inuits many Northern Athabascan bands and many NDN bands in BC) are not covered by this and may not bring their feathers across into the US without possibly having them confiscated by US Customs. Even though these bands are recognized by Canada as aboriginal they are not issued a card by the Canadian governmant so they do not qualify to be treated the same by the US.
Sad but true!
