HOWever... What I really need to become a better terrorist, is some good commonly-available poison. The South Americans have got curare and poison frogs and a couple of other things I can't remember that are nice and deadly in nice small microgram quantities, but there's hardly anything a good ol' boy like myself, living up here in the temperate zone, can find in the backyard that might work.
HOWever... There is a fascinating quote in Cabeza de Vaca's "Naufragios" about how the Indians in the Texas region had a bush (NO PUNS, WISEASSES -- I CAN SMELL YOU THINKING) that that would kill *anything*. He reported that they used it for arrow poison and that it was so poisonous that if the leaves even fell into water that animals drank it would kill them.
You Texicans know of anything like that down there?
Yep. Great way to break the mother-in-law's cats of chewing on the potted plants. Further resopndant sayeth not.
