would anyone here like to provide another anthrax scare?
I keep a small number of cattle. One of them is a yearling heifer who likes to have her chin and brisket scratched. Come visit me; I'll introduce you to Summer the cow, and after you've made good friends, you can write a letter without washing your hands first. A dusting of talcum, and voilà a genuine verifiable anthrax letter... which will pass the CDC and everything.
I don't recommend it just now. But this stuff is endemic throughout the world in populations of ruminants; if any congressman would like to get his name in the paper, all he need do is scan for letters from his rural constituents.
Tempest in a teapot.
