I want to start a boycott of Oregon beef. Or THEIR beef. Let's hit them right

5. unless they direct-market or are part of some co-op or other entity that does direct,

it is doubtful you can source back to individual ranches as a customer. most range cattle go through at least one or two other growing locations before slaughter. and then the cuts you buy retail are likely from different animals - and this is especially true if you buy chubs of hamburger (I do not recommend buying ground beef this way, it is the most likely way to get food poisoning from meat, other than chicken)

most beef is marketed as a commodity and you would have a hard time sourcing it back to the rancher, (though it can be done if there were some kind of outbreak)

AND from what I have read, the ranchers in Oregon didn't want those yahoos to come up there anyway. AND most of the yahoos aren't even really ranchers!

you COULD find a local source of beef in your area, see what you think about their politics or other world views and buy from them.
