Got a solicitation for donations to the anti-hunting group, The Humane Society of the United States. They sent a pack of address labels with the solicitation, as so many do now days.
There target of the day is "puppy mills" but they are known for funneling funds for Anti-hunting legislation.
The solution, do what I did;
Took their postage paid envelope and stuck a pic of me my daughter and a dead bear, in the envelope. Then put my freshly delivered return address sticker on the envelope so they would know to take me off there mailing list, the rest went in the trash.
That and the satisfaction that I cost them another $.44 kinda made my day.
