Wilford Brimley thinks banning cockfighting isn't the right thing to do. The grandfatherly actor and Quaker Oats pitchman attended a rally Saturday to voice opposition to Proposition 201, a proposed Arizona cockfighting ban expected to be approved Tuesday.

Approval could lead to more laws restricting the use of animals, such as prohibiting the use of dogs for hunting, Brimley, 64, said.

"Once an idea like this gets started, I don't know where it's going to end," he said.

Cockfighting is legal in Arizona, New Mexico, Oklahoma, Missouri and Louisiana. Missouri voters also will consider a ban Tuesday.

Brimley, who lives in Utah, said he visits Arizona to attend cockfights.
