Apparently no black guns, accessories for black guns or even literature for the promotion of any black guns. There is a long list of businesses who are no longer taking their booth and the list continues to grow.
While surfing a few shooting related web sites it became obvious that a boycott by shooters, hunters and regular show-goers is growing fast too.
My hunting buddies and I go every year but this year we'll help the cause by joining the boycott. Instead, I sent a nice donation to the NRA. It may only be symbolic but it's the best I can do at the moment.
