Re: arsenic (and old 'shrooms?)

Gardeners like it because it has already composted horse manure 
in it. Plus whenever it rains, they get a bumper crop of mushrooms 
since some of the spore remains viable for a time. You can't believe 
how bad this stuff smells, though. Driving by the mushroom plant at 
70mph, windows rolled up, the smell will linger in your vehicle for 
hours afterward. I don't see how anyone works there. That can't be 
good.
