In Alaska many Native communities are dry or have some version thereof (some are package sales only). However, in all cases it is something the community itself voted in. Some communities have changed their ordinances back to 'wet'; in some cases they changed back to dry.

I don't see how any outside body, whether federal or otherwise, can make such laws. Kind of like forcing one's own version of democracy on a country- which is bound to resist it.

As in almost everything, education is the key. When native elders become convinced of harmful practices they will convince the community- from that point it is only the occasional miscreant that has to be punished.

At least, that is how it works in Alaska.
