I cover my piles with an outer layer of straw, weedblock plastic cloth, then more straw, to block out the strong ammonia smell. This way my neighbors do not have to experience it. Then I let it cook. The higher heat helps to destroy unwanted weed seeds, bad bacteria, etc., and its a way to break down the material faster. Some gardeners want this. On the other hand, cooler temps conserve some of the nitrogen, which other gardeners want. Do you have a compost thermometer? I was amazed at how mine climbed to 138 degrees F! On my last batch I did get a 'garbagey' smell, so I turned it to get more oxygen in, and that got rid of that smell.
