This border fence brought to you by ... PETA?

Border-fence proponents have a new argument for its installation: advertising revenue.  Not only will it deter illegal immigration through physical intimidation, but the government can sell advertising on it explaining why Mexicans shouldn’t want to live in the US anyway.  The sponsor?

While many view the contentious border fence as a government fiasco, an animal rights group sees a rare opportunity.
People for the Ethical Treatment of Animals plans today to announce an unusual marketing pitch to the U.S. government: Rent us space on the fence for billboards warning illegal border crossers there is more to fear than the Border Patrol.
The billboards, in English and Spanish, would offer the caution: “If the Border Patrol Doesn’t Get You, the Chicken and Burgers Will — Go Vegan.”
“We think that Mexicans and other immigrants should be warned if they cross into the U.S. they are putting their health at risk by leaving behind a healthier, staple diet of corn tortillas, beans, rice, fruits and vegetables,” said Lindsay Rajt, assistant manager of PETA’s vegan campaigns.

Far be it from me to get in the way of dissuasion, but maybe PETA should check its numbers first.  Mexico has the shortest life expectancy in North America, trailing Canada by over five years and the US by almost three.  In fact, according to the CIA World Factbook, no nation in Central or South America beats either Canada or the US, and most fall short of Mexico.
Still, why not have PETA waste its money on sponsorship of the fence?  It beats some of the other purposes they have for their funding.  If they can con celebrities into posing nude for their propaganda, maybe they can convince would-be border crossers to stay home.
