Hi Mark,

just a comment on the heat. i finally have come up
with a compost pile that gets what i would call "hot".
i have a small lawn service and get literally tons of
lawn clippings. i started a couple composts that are
almost 100% grass clippings, not much else (it's
summer, so no fall leaves, wood chips, etc. mixed in).

to see if it was heating up i simply jammed a handle
from a garden tool about 12 inches into the pile, and
stuck my hand in there. it was hot enough, i had to
withdraw my hand pretty quickly.

i should get more scientifical and stick a temperature
gauge in there, i spoze.

peas,
