I guess everyone knows not to burn poison ivy?? The smoke, even from a long
distance can severely damage a susceptable person's lungs and land them in
the hospital with serious problems. I have seen it happen.

Roundup first came up it was supposed to "bind to the soil particles", this
doesn't make me overly comfortable, but perhaps it prevents it from washing
into streams or the water table.
