That's really all I can think of, unless you want to contact other papers. You've done all the ones in your area, but other local papers (Greeley Tribune, etc) might pick up the story too. I think you've contacted the main ones though. PETA was a good move too. I don't know of anyone else to contact. I really hope that the people you have contacted will help you.

That's terrible that they're doing this and that they even CAN.
