Sounds like Cultural Appropriation to me.
A Potlatch is an indian native American get-together - like a ceremonial feast.
How culturally insensitive of you to reside in a town that appropriated that term!
I bet they don't even have a casino or a discount cigarette outlet there.

What have you been inhaling? I have a sister named Elizabeth Warren. Actually, just north of potlatch the Indian Res sold fireworks and tobacco tax free. We didn’t use tobacco but we sure bought the fireworks which were not to be found elsewhere in our part of Idaho.
